Abstract

Abstract

Triaxial shear tests are done before and after vibratory load actings, and the testing samples are the red clay inXiamen. The effects of vibratory loading on sample' s cohesive force, internal friction angle, shear strength equation and theability to resist side distortion etc are studied by analyzing test data. After vibratory load actings, the cohesive strength indexand internal friction angle of the sample are decreased by 51. 72% and 50% respectively;and the shear strength curveshifts down obviously under same testing conditions.The results show that vibratory load acting is disadvantage tostabilization and bearing capacity of red clay.The research conclusions have theoretic and practical significance for us toprevent geotechnical engineering disasters and geologic disasters
