红粘土细观力学特性的颗粒流模拟
Simulation of Mesoscopic Mechanic Properties on Red Clay by Using Particle Flow Code
摘要
Abstract
As a kind of special engineering soil,the research regarding the red clay is mainly focused on the macroscopic mechanical response.However,contrast to the macroscopic mechanism,the mesoscopic mechanism,which was used to explain the red clay mechanical properties,has been less analyzed.By referring to the red clay macroscopic mechanism indicator produced by the indoor triaxial test,this paper has proposed the triaxial test based on the PFC3 D particle flow code numerical simulation.Besides,it also has calibrated some mesoscopic mechanical parameters such as the red clay particles contact force,contact modulus and bond strength,etc.This paper not only achieves the unification of the mesoscopic mechanical parameters and macro mechanics index,but also uses themacroscopic parameter to reflect the essential characteristics of the mechanical properties.关键词
