Abstract

In order to research the microscopic variations of weathered phyllite fillers in the bearing plate experiment, the spheroids of intergranular interaction model and the particle flow theory of discrete element method were adopted to simulate soil particles in this paper. Calculation model of weathered phyllite with 55% rock content was established by PFC2D. And the microscopic parameters of the granular unit were further revised on the basis of laboratory experiments. Besides, the stress-strain relationship and the microscopic properties between particles were studied under loading and unloading conditions both by numerical simulation and laboratory test. Results show that the resilient modulus and peak strength of weathered phyllite fillers were closely related to the microscopic parameters in the numerical model. Furthermore, the numerical simulation results coordinated well with the test results. The research results in this paper could provide references for further exploration of the properties of weathered phyllite fillers.
