A Revising Method of Shear Strength of Soils in Direct Shear Test

Xin Qiu

Abstract

Considering the change conditions of shear areas in shear test,the shear stress equation has been established.According to the in-door shear test data and shear stress equation,the change law of shear strength was given on the base of comparing the two (cases--)the shear areas of the soils sample is either changed or unchanged.In the end,coefficient of shear strength was defined and its change law was given.The study has proved that the accuracy of shear strength was improved by the application of coefficient of shear strength.
