Abstract土石混合体是非均匀、非连续的,在外力作用下,其内部应力分布是不均匀的,其真正的边界条件是等应力边界条件。现有的土力学实验机都是刚性边界加载,即按等位移边界条件加载,不适用于研究非均匀材料。基于此自行研制了等应力边界加载实验机,通过采用柔性压头和柔性底座施加等应力边界条件,研究两种边界条件下土石混合体抗剪强度参数的差异,同时采用课题组自行研发的CDEM(Continuum-based Discrete Element Method)计算软件,开展了相应的数值计算,结果表明,传统的等位移边界条件所得不均匀地质体参数明显大于同等条件下等应力边界条件所得参数(约20%),是偏不安全的。
