某深埋隧道地应力测量及岩爆可能性分析

In-situ Stress Measurement and Rockbust Possibility of a Deep-buried Tunnel

根据隧道区一个深钻孔的水压致裂法地应力测量结果,对隧道区的地应力水平及隧道围岩稳定性做出了评价,并根据测试区域的地应力条件,对隧道施工期间发生岩爆的可能性进行了判断,为隧道设计提供依据。

According to the results of crustal stress measurement by using hydraulic fracturing method,the evaluation of the level of crustal stress and the stability of the rock in a deep tunnel are made.Based on the crustal stress condition,the possibility of rockburst in the tunnel is assessed,which can provide an important reference for the tunnel design.
