Research Abstract |
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.
