某隧道区地应力测量与岩爆分析

Geostress determination and rockburst analysis for an expressway tunnel

介绍了某高速公路隧道区2个钻孔(深度为280和567 m)的水压致裂法地应力测试结果,并就施工期岩爆发生的可能性和隧道围岩稳定性进行了初步分析。

Results of hydro-fracturing in-situ stress measurement of two holes in an expressway tunnel rockmass are presented. The possibility of rock-burst during excavation and the tunnel stability are also analyzed.
