Cyclic torsional shear tests for banking soils in housing lots were conducted to demonstrate the strength and shear modulus during earthquakes. The banking soils were taken at nine sites from Hokkaido to Kyushu. Test results showed undrain cyclic shear strength and shear modulus after cyclic loading increase with degree of compaction and fines content. Based on these test results, deformation of three banking lands where severe damage occurred during the Great East Japan Earthquake, were analyzed by residual deformation method and Newmark method. Analyzed deformations are fairly coincided with the actual deformations. Stability analysis for an embankment which had been deformed before the earthquake and failed due to the earthquake was also conducted.

通过对某住宅区堤围土的循环扭剪试验，研究了地震作用下堤围土的强度和剪切模量。在从北海道到九州的9个地点采集了银行土壤。试验结果表明，不排水循环剪切强度和循环荷载后的剪切模量随着压实度和细粒含量的增加而增加。根据这些试验结果，采用残余变形法和Newmark法对东日本大地震中受损严重的三处堤岸的变形进行了分析。分析变形与实际变形吻合较好。并对一个震前已发生变形的路堤进行了稳定性分析。
