摘要
随着地下工程作业深度的增加,岩体的原岩应力也越来越大。为了保证工程作业时岩体的稳定,讨论了原岩应力的形成、影响原岩应力的因素及几种原岩应力的测量方法,并对这几种测量方法进行了比较,提出今后测量原理原岩应力应改进的地方。
As underground engineering is deeper,the in situ rock stress will become greater.To maintain the stability of rock body during the engineering operation,the authors discuss the formation of in situ rock stress,affecting factors of in situ rock stress and several measuring methods of in situ rock stress.The paper compares these measuring methods and points out where improvements can be done.
