基于离散元理论的土石混合料剪切特性研究
Study shear behavior of soil-rock mixture based on discrete element method
摘要
Abstract
In order to study shear behavior of soil-rock mixture,biaxial models of soil-rock mixture are established by PFC2D based on discrete element method theory to analyz shear behavior of soil-rock mixture with different conditions of load and rock content,and Fourier series is introduced to study distribution law of fabric in strong and weak force chains.The results show that the shear strength and dilatancy behavior of soil-rock mixture increase with the increase of rock content,strong force chains play a vital role to bear axial load,finally frictional angle values of soil-rock mixture with different rock content are confirmed by a series of biaxial test.关键词
