本文中叙述的模型试验,主要是模拟在具有两组正交节理的岩体中开挖隧道时,由于初始应力场中不同的水平构造应力的作用,隧道围岩的稳定性特征。通过对试验结果的分析得到几点相应的结论。
The model tests described in this article mainly simulate the stability characteristics of the surrounding rock of a tunnel due to the different horizontal tectonic stresses in the initial stress field when tunneling in a rock with two orthogonal sets of joints. Through the analysis of the experimental results obtained a few corresponding conclusions.
