应用弹性力学原理求解发生岩爆的强度准则

The intensity criterion of rock burst resolving with elastic mechanical mechanism

阐述了岩爆是高地应力环境岩石地下空间围岩积聚的应变能突然释放所引起的动力失稳现象,通过对弹性力学原理及强度破坏准则的研究,并借助于弹性力学中平面问题的极坐标解答,从而导出岩爆发生的条件。

It illustrated that rock burst was dynamic bucking phenomena provoked by rock underground space adjacent rock accumulated strain energy releasing suddenly in high strata stress environment. Through studying on elastic mechanical mechanism and intensity damage criterion, combined with polar coordinate resolving in plate problems of elastic mechanic, the rock burst occurring condition was deduced.
