Research Abstract

Stress-controlled cyclic direct shear test to simply estimate cyclic resistance ratio (CRR) of cohesive sandy soil such as treated soil by lower cost was proposed in this study. Cyclic shear tests for various sandy soils and clay were conducted. The CRR obtained by proposed test gave a good agreement with the CRR obtained by conventional cyclic test of hollow cylinder test. In addition, the problem to be solved for practice application such as a reasonable criteria decision of double amplitude horizontal displacement for triggering liquefaction was pointed out.
