在云南省水电建设中,为了研究地下洞室围岩的承载能力和稳定性,我们曾进行岩体应力的测试工作以探索岩体的初始应力状态及围岩应力的分布情况。在早期主要是进行表面应
In the construction of hydropower in Yunnan Province, in order to study the bearing capacity and stability of the surrounding rock in underground caverns, we conducted tests on the stress of the rock mass to explore the initial stress state of the rock mass and the distribution of the surrounding rock stress. In the early stage is mainly the surface should be
