• Influences of geogrid stiffness and its aperture shape on load-settlement behavior and surface deformation of reinforced sand

  AUNG AUNG SOE, TACHIBANA SHINYA, KUWANO JIRO

  Load settlement behavior, bearing capacity improvement and surface deformation characteristics of geogrid reinforced soil were investigated through experimental study. Rigid circular steel plate was used as a model footing. In model experiments, it included one unreinforced test and four reinforced tests; one with triangular geogrid and three with biaxial geogrids. Test results show that triangular geogrid reinforcement outperforms biaxial geogrids of almost same unit weight. For biaxial geogrids, larger bearing capacity improvement was noticed with geogrid of higher tensile strength. Uniform surface deformation was observed with no reinforcement and triangular geogrid reinforcement, while higher non uniformity was observed with stiffer biaxial geogrid reinforcements.

• Effect of prestress in geogrid on stiffness of confined-reinforced earth

  HO MANH HUNG, TACHIBANA SHINYA, KUWANO JIRO

  Large earthquakes often lead to large differential settlement between bridges and their approaches. In some of these cases, emergency vehicles cannot pass the unevenness after earthquakes. In order to mitigate this problem, confinedreinforced earth (CRE) method was introduced in subgrade layer, at the bottom of pavement layer of road structures. Some laboratory prototype scale model test with various prestress in geogrid layers were carried out to investigate the effects of prestress on deformation of confined-reinforced layer due to differential settlement. The levels of prestress is applied via prestrain set as 0%, 0.016%, 0.05% and 0.1% in elongation. The results show that the prestress in geogrid plays an important role in reduction of differential settlement between bridges and their approaches.

  TACHIBANA Shinya, KUWANO Jiro, ISHIGAKI Tsutomu, TATTA Naoki

  In the confined-reinforced earth method, a composite layer which has a high stiffness is constructed in the subgrade to support the pavement. This layer consists of granular materials, geogrids and confining members. Compacted granular materials are reinforced between some geogrids and are further confined by some members. Construction of this layer beneath the asphalt pavement is expected to prevent unevenness even if the road embankments settle due to earthquake. In this study, a series of model tests was performed for the purpose of investigating the reinforcement effects against different designs such as a layer thickness and an introduction of pre-stress in the confining members.

• Shear strain distribution in soil around geogrid during the unloading-reloading pull out test

  Nguyen, G.H, Kuwano, J, Izawa, J, Seki, S, Tachibana, S

  The soil-geogrid interaction process was analyzed by the Particle Image Velocimetry furthermore spatial discretization scheme in finite element method to understand about the dilatancy mechanism and shear strain distribution during unloading-reloading process. In this test the geogrid was pushed back and forth at three stages of pullout test: before peak, at peak and at residual part to simulate the seismic activities. Results showed that the shear strain concentrated in front of transverse ribs and upper apart of pullout box. The dilative behavior appears in front of transverse ribs and contractive behavior exits at behind of these bars. The alternative soil dilatancy-contraction distribution in between the two transverse ribs can be seen throughout the length of geogrid.

• Study of spatial discretization scheme in unsaturated soil/water coupled analysis

  KANAZAWA Shinichi, TACHIBANA Shinya, KAWAI Katsuyuki, OHNO Shintaro, IIZUKA Atsushi

  Many of earth structures on the ground keep stability in unsaturated state. Moreover, these structures are exposed to drying and wetting conditions and changes in soil moisture always occur. Therefore, the constitutive model with unsaturated soil mechanics is needed for predicting the elasto-plastic behavior of the earth structures for a long term. The objective of this study is developing soil/water coupled F. E. analysis with unsaturated soil mechanics. In this study, the constitutive model proposed by Ohno et al. is used. Their model can express typical behavior of unsaturated soil, such as shrinkage on drying process, collapse on wetting process, and the effects of hysteresis on soil-water retention characteristic curve, and have the flexibility for dependencies on soil properties. Moreover, isoparametric element is applied on spatial discretization to preventing the dependency on mesh, which can be seen in the Akai and Tamura's method. This simulation method allows us precise prediction of the behavior of unsaturated earth structures.

• Influence of vegetation uptake on the deformation of ground

  KAWAI Katsuyuki, YAMADA Ryotarou, IIZUKA Atsushi, TACHIBANA Shinya, OHNO Shintaro

  Empirically, it is known that the vegetation influences on the earth structure. Kawai et al. focused on the effects of water uptake induced by the vegetation. They regarded it as an effect of decreasing soil moisture and applied the effect to unsaturated soil/water coupled F. E. analysis. In this study, the soil/water coupled F. E. analysis code is rearranged with the constitutive model for unsaturated soil proposed by Ohno et al.. In their model, the effective degree of saturation are applied as a parameter expressing stiffness of unsaturated soil to enable application of unsaturated soil mechanics to actual problem in geotechnical engineering site. To verify the applicability of soil/water coupled analysis, the accident that the vegetation uptake work brought about the non-uniform settlement of the ground and damaged the building in Poland are simulated. Consequently, it was found that the uptake increased suction and encouraged non-uniform settlement of ground surface. Its effects appeared prominently in a dry ground having low groundwater level and much uptake. This method is effective to understand the effects of vegetation.

• The influences of uptake of vegetation on the ground

  KAWAI Katsuyuki, IIZUKA Atsushi, SHIMONAGA Katsuyuki, TACHIBANA Shinya

  It is known that the vegetation is effective in preventing slope failure. In this study, we focus on the vegetation uptake from ground and show the way to estimate its effects on the ground quantitatively. The effect of uptake can be regarded as reduction of water content within soil. The ‘root element’, where the reduction of water content occurs, is applied to the existing code of soil/water coupled finite element analysis with unsaturated soil mechanics. To estimate the effects of uptake, three kinds of conditions, such as the amount of uptake water, the initial degree of saturation of the ground, and groundwater level are provided. Consequently, it was found that the uptake increased suction and encouraged non-uniform settlement of ground surface. Its effects appeared prominently in a dry ground having low groundwater level and much uptake. This method is effective to understand the effects of vegetation.

• ELASTO-PLASTIC CONSTITUTIVE MODEL FOR UNSATURATED SOIL APPLIED EFFECTIVE DEGREE OF SATURATION AS A PARAMETER EXPRESSING STIFFNESS

  OHNO Shintaro, KAWAI Katsuyuki, TACHIBANA Shinya

  To predict the long term elasto-plastic behavior of unsaturated earth structures, the constitutive model, which can express the following typical behavior of unsaturated soil, is needed. One is shrinkage and stiffness increase due to suction increase, second one is collapse with stiffness decrease due to suction decrease, and the last one is the influences of suction history relating to the hysteresis of soil-water retention characteristics. In this study, a constitutive model of unsaturated soil applied the effective degree of saturation as parameter expressing stiffness was proposed. The model showed good agreement with the experimental results and the appropriateness of the model was demonstrated.

  桑野 二郎, 橘 伸也, 横田 聖哉, 中村 洋丈

  The purpose of this study is to estimate settlement of highway embankment during construction and compare it with the field data measured at the 90 m high embankment of the second Tomei Express way in Shizuoka. The mechanical characteristics have been briefly modeled referring to the results of one-dimensional compression tests on materials which are used in constructed embankment. Then, the amount of settlement of the embankment is estimated considering the effects of degree of compaction. It is found that the settlement at the center of the embankment can be estimated properly even by the simple method of one-dimensional calculation.

  歴史的遺産は、大地震や大降雨などの自然災害に耐えて数百年以上残ってきたことから、遺跡の置かれた地域の環境に良く適合した技術を伝えている。いわば長期的に見てレジリエントな技術を伝えている意味で工学的にも貴重である。しかしながら、近年世界で急速に遺跡の劣化・崩壊が進んでいる。その原因の一つが、基礎地盤内の水分変動による地盤変形と塩類風化の促進である。これらは、とくに①乾季と雨季が繰り返し、雨季には地表が水浸する事もある東南アジア地域と、②最近の灌漑により地下水位の上昇が顕著なエジプトなどの乾燥地域で顕著である。本研究の目的は、これら両地域の代表的な遺跡構造物の地中水分変動による劣化・崩壊を地盤工学の最新知見により解明し、合理性の高い遺跡修復・保全技術を開発する事である。なお、本研究の進展により、横須賀ドライドックなどの明治初期の構造物を対象として、構造物変形モニタリング技術の開発も行う。 本年度は最終年度として、昨年度までの2年間の研究成果を踏まえ、次のような研究計画を立てた。エジプトでの研究は政変による社会混乱と治安悪化のため、現地での研究は差し控え、共同研究者であるメノウファイア大学理学部のGamal Kamh教授を招聘することによる連携研究とし、国内において昨年度持ち帰った塩類試料の分析を中心に実施することとした。タイ・アユタヤ遺跡において一昨年度取得したWat Yai Chai Mongkhon寺院とWat Langkha Khao寺院のストゥーパの3次元図と比較しうる2年経過後の3次元図を取得し、これらを比較することによって、変形モニタリングが可能かを詳細に検討することとした。また変形が明瞭に示された場合、その要因としての遺跡直下の地盤構造を把握するために、表面波探査の適用を検討した。 タイでの調査は、2015年11月に開催予定のISEEE(International Symposium on Engineering, Energy and Environment)に合わせて実施する予定であったが、研究代表者の急逝により頓挫した。研究代表者の意思を貫くためにも、別途予算を得て最後まで成果を出したいと考えている。

  The main objective of the study is to investigate the mechanism of formation and extension of internal erosion and water pathway in the backfill of earth structure by water penetration due to repeated rainfall. In order to evaluate effects of soil grains escaping from the specimen, a special permeability test was conducted. When hydraulic gradient exceeded certain value, fine particles started to flow out of the specimen. Turbidity of the drained water can indicate the degree of currently progressing internal erosion. Even small degree of internal erosion caused significant decrease in penetration resistance.
