摘要
假设岩石在峰值强度前无损伤,峰值强度后为线性损伤,根据Lemaitre的应变等效原理,严格地导出圆形洞室发生岩爆的解析解,给出了洞室发生岩爆的临界载荷及临界损伤区大小,研究了升降模量比E/λ对岩爆的影响。
Under hypothesis of linear damage of rock after its peakstress, a closedform solution is given of circular chamber rockburst. The critical load and damage zone size of rockburst have been got. The effect of E/ on the rockburst has been studied.
