摘要
洞室发生岩爆后围岩总要留下破坏痕迹，岩爆往往造成劈裂破坏或剪切破坏。只要知道岩爆形成的破坏面的几何尺寸和破坏机制，就有可能通过反分析求得岩体开挖前的应力状态。本文简要叙述了我们在这方面的初步研究成果。
After rockburst occurs in the tunnel , Some traces always reserve on the wall. Destructionsof rockburst are in the form of split or shear.If only we make sure the size and mechanism ofdestructive faces shaped by rockburst,we can obtain the stress state of rock mass before blasting,through back analysis.This paper briefly discusses the elementary results of reserch in the field.
