摘要
采用有限差分软件FLAC^(3D),以摩尔—库仑准则为屈服条件,建立了二维有限差分数值模型,对比分析不同围岩级别情况下,初期支护喷射混凝土厚度对不同级别围岩的支护作用效果,从而选出不同围岩级别下适宜的喷射混凝土厚度。
In this paper,the finite difference software FLAC3 Dis used to establish a two-dimensional finite difference numerical model with Mohr-Coulomb criterion as the yield condition. In order to compare and analyze the effect of the thickness of the shotcrete on the support of different levels of surrounding rock,so as to select the appropriate shotcrete thickness under different surrounding rock level.
