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。进行了卡川市LBGeikePond的沙质泥土的空心圆柱测试和三轴压缩试验，以评估设计测试路堤设计的强度特征。然后，使用大三轴细胞和大土壤罐进行渗透性测试，以识别土工格里德对土壤颗粒运动的预防作用。2。使用新的改进技术进行灌溉堤防构建了一个测试路堤。从测量和发掘观察中可以观察到卡川市的Togeike-Pond。3。用沸石凝灰岩和水泥浆开发了纯化复合材料，以评估纯化的性能和机理。使用该材料的面板应用于测试路堤以获得足够的水纯化性能。4。对4种类型进行了模型摇台测试，以观察溢洪道上的抗震性能进行灌溉路堤。通过评估企业重量，截面形状和增强的企业点，用增强型B和D模型在响应和残留位移上表现出良好的性能5。进行了溢洪道的三维FEM动态响应分析，以识别来自不同溢流材料的响应位移分布的巨大差异，并注意具有较小刚性（例如PVC）的材料的大垂直响应位移。
