| 摘 要： | 地应力是隧道等岩石工程稳定性设计与评价的重要基础资料，在重大工程设计与施工前，需进行地应力测量，为工程设计提供依据。岩爆常发生在强度高、质地坚硬、干燥且较完整的弹脆性岩体中。采用水压致裂法测定地应力，在此基础上用Russense法、陶振宇法和Wet能量指数法综合预测隧道发生岩爆的几率，为工程开挖提供参考。

| Abstract: | As an important basis material of stability design and evaluation of the rock engineering as tunnel,ground stress needs to be measured before design and construction of major projects,in order to provide a basis for engineering design.Rock burst often occurs in elastic-brittle rock mass with high intensity,hard,dry,and complete texture.Hydraulic fracturing method is used to measure ground stress,on this basis,Russense method,Tao Zhenyu method and Wet energy index are used to integrally forecast the probabil... |
