用液压破裂法测定岩体应力,具有不必套钻取芯,不受测量深度限制、不必测量岩体弹性常数等特点而优于其它方法。作者在室内试验的基础上创造了一种新测试方法,只要运用液压破裂法所测数据即可计算出不透水岩体的三维应力状态。
The hydraulic rupture method is used to determine the stress of rock mass. It is superior to other methods in that it does not need to drill a coring core and is not limited by the measurement depth and does not need to measure the elastic constant of the rock mass. Based on the laboratory tests, the authors create a new test method that can calculate the three-dimensional stress state of impervious rock mass by using the data measured by hydraulic fracturing method.
