岩体应力状态的形成是由于各种成因不同的力(重力、构造力、热力等)作用于结构和性质不均匀的坚硬岩体的结果。实测资料表明:岩体中彼此相距不远的点,其应力分量的大小可能相差十倍甚至更大。这时,应力符号往往改变。裂隙是决定岩体应力状态的因素之一。在进行应力研究的现场试验时,所有裂隙被详细 The formation of stress states in rock masses is the result of various forces (gravity, tectonic, thermal, etc.) acting on hard rock masses with heterogeneous structures and properties. The measured data show that the points in the rock mass not far away from each other may have a stress component of ten times or more. At this time, the stress signs often change. Cracks are one of the factors that determine the stress state of rock mass. In the field test of stress studies, all fractures were detailed
