摘要
通过对我国西部一些重点工程的地应力测量,大致得出西部工程的应力状态,并从实测地应力资料出发,采用现有的、普遍应用的岩爆判别准则,对这些工程在施工开挖期间的地下工程进行岩爆预测分析。
Through measuring geostresses at several key projects in West China, the stress states of West Chinas projects are obtained. And based on the in-situ measured geostress data, the widely used current criterion for distinguishing rock bursts is adopted to predict rock bursts for some underground projects during the construction excavation period.
