项目摘要

1. The hollow cylindrical torsional test and the triaxial compression test on improved sandy mud soil of the lbgeikepond in Kakogawa city were conducted to evaluate strength characteristics for design of a test embankment. Then, the permeability tests using large triaxial cell and large soil tank were performed to recognize the preventing effect of geogrid on soil particle movements.2. A test embankment was constructed using the new improving technology for irrigation embankments iat the Togeike-pond in Kakogawa city Satisfying enough performance and behavior were observed from measurement and excavation observation.3. A purification composite material was developed with zeolitic tuff and cement slurry to evaluate the performance and mechanism of purification. The panels used this material were applied to the test embankment to obtain sufficient performance of water purification.4. Model shaking table tests were conducted on 4 types to observe earthquake resistant performance on spillway for irrigation embankments. As a result of evaluating firm points of weight, section shape and reinforcing, models B and D with reinforcement showed good performance on response and residual displacement5. The three dimensional FEM dynamic response analysis of spillway was performed to recognize the large difference for response displacement distribution from different spillway materials and to note the large vertical response displacement for materials with small rigidity such as PVC.

1. 对加古川市lbgeikepond改良砂泥土进行空心圆柱扭转试验和三轴压缩试验，以评价试验路堤设计的强度特性。然后，利用大型三轴室和大型土箱进行了渗透性试验，验证了土工格栅对土颗粒运动的阻止作用。 2．在加古川市Togeike池塘采用灌溉堤坝改良新技术建造了试验堤坝，通过测量和开挖观察观察到了令人满意的性能和性能。 3．用沸石凝灰岩和水泥浆开发了净化复合材料，以评估净化性能和机理。采用该材料的板材应用于试验路堤，获得了足够的水质净化性能。 4．对4种类型进行了模型振动台试验，观察灌溉堤坝溢洪道的抗震性能。通过对重量、截面形状和加固等坚固点进行评估，带加固的模型 B 和 D 在响应和残余位移方面表现出良好的性能5。对溢洪道进行了三维有限元动态响应分析，以识别不同溢洪道材料的响应位移分布存在较大差异，并注意到 PVC 等刚度较小的材料的垂直响应位移较大。
