Simulation Study on Direct Shear Test Mechanical of Properties for Fine - Grained Soil

Xinhua Xiang

Abstract


In order to study the fine grained class engineering properties of filled soil, direct shear test of particle flow model was established. It analyzed the influence of experimental model size, particle size, coarse grain shape of cohesive soil, coarse particles and viscous particle microstructure parameters on the macroscopic mechanical properties (mainly for the stress-strain characteristics). The results showed that there was a positive correlation relationship between the shear modulus and the average particle size of the sample.The average about peak intensity of the sample first increased as feature length ratio then decreased. The greater initial plane porosity rate, the smaller the peak strength of rock and soil and the shear modulus.
