随着四化建设的迅速发展,修建高坝、大跨度高边墙的地下工程的数量越来越多,规模越来越大,促进了岩体力学的发展。 岩体变形特性的研究,概括分为动力法和静力法。 动力法最常用的是声波和地震两种方法,其主要优点是测试迅速,方法简便,仪器轻便。目前,两种方法同时并用,大面积岩体采用地震法测试,局部节理裂隙、断层则采用声波法控制。但这两种方法均不能反映岩体在荷载作用下的变形特征。
With the rapid development of the four modernizations, there are more and more underground works to build high dams and long-span high-side walls, and the scale is getting larger and larger, which promotes the development of rock mechanics. Rock deformation characteristics of research, generalized into dynamic and static method. Dynamic method is the most commonly used sonic and seismic two methods, the main advantage is the rapid test, the method is simple, lightweight instrument. At present, the two methods are used together. Large area of rock mass is tested by seismic method, local joint cracks and faults are controlled by acoustic method. However, neither of these methods can reflect the deformation characteristics of rock mass under load.
