一、前言隧道是否稳定取决于临近于它的围岩是否稳定,而恰如其分的支护系统又促成它获得必要的稳定性。这个问题既是地下工程的岩石力学研究方法中的重要课题,又是施工与设计者们普遍关心的问题。
I. INTRODUCTION The stability of a tunnel depends on the stability of the surrounding rock adjacent to it, and the proper support system leads to the necessary stability. This problem is not only an important issue in rock mechanics research methods of underground engineering, but also a common concern of constructors and designers.
