高地应力下岩体的破坏特征分析

Destruction characteristic analysis of rock mass under high ground stress

结合工程实践经验,对高地应力下岩体的破坏特征进行了分析研究,研究发现,其破坏分硬岩和软岩两种,硬岩下有时会发生岩爆,软岩下可能会发生挤压大变形,都给施工造成了困难,指出在施工中都要对高地应力进行逐步释放,并做好施工辅助措施,以确保施工安全。

Combining with project practice experience, the author analyzes and studies the destruction characteristic under high ground stress. Research shows that its destruction divided into two kinds of hard rock and soft rock, and the hard rock occurs rock burst some times, the soft rock may occur squeezing big deformation, which createdifficulty to the construction, points out that it is necessary to release slowly the high ground stress in construction and do well construction assistant measures, so as to ensure construction safety.
