为了保证地表工程,特别是地下工程的安全性和经济性,了解和掌握岩体初始应力状态是非常必要的。岩体初始应力;就是天然岩体在工程建设开挖之前所具有的自然应力状态,通常也叫做地应力,主要决定于重力场和构造应力场。 研究岩体初始应力有两种方法,即理论的方法和经验的(实测的)方法。理

In order to ensure the safety and economy of surface engineering, especially underground engineering, it is necessary to understand and master the initial stress state of rock mass. The initial stress of the rock mass is the natural stress state of the natural rock mass before the excavation of the engineering construction. It is usually also called the ground stress, which mainly depends on the gravitational field and the tectonic stress field. There are two methods for studying the initial stress of rock masses, namely theoretical methods and empirical (measured) methods. Management
