| 摘 要： | 岩爆是岩体高应力区的一种重要地质现象,是地下工程建设中必须关注的重要地质工程问题之一.文中提出3个最能控制岩爆发生的指标:围岩二次应力的最大主应力与岩石抗压强度比、岩爆倾向性指数和岩体完整性指数.以这3个指标为影响因素,确定了岩爆发生等级的判断标准.在此基础上采用可拓方法对岩爆的发生及等级进行了综合判断,并运用已经完成的工程实例进行了验证.

| Abstract: | Rockburst is a common geological phenomenon in the high geo-stress area.It is also one of geological problems cared by researchers in underground engineering.This paper presents three factors: the ratio of the second maximal stress of adjacent rock mass to the uniaxial compressing intensity of rock samples, the rockburst proneness index and the integrity index of rock mass,which have great influence on rockburst.Moreover,the judgement criterion of rockburst intensity was established.Then the rockburst is ev... |
