巷道泥石流形成机理的探讨

Exploring the Forming Mechanism of the Roadway Debris Flow

本文介绍了巷道泥石流这种新的地下工程灾害。通过分析国内发生的多次巷道泥石流事故资料,总结出其发生条件和一般特征。巷道泥石流实质上是大范围的岩体由于断层构造、压力水冲刷岩石自重和不适当的施工处理方法综合作用引起的突发性失稳破坏所产生的结果,并详细分析了其形成过程,据此提出了预防巷道泥石流的具体措施。

This paper introduced a new underground engineering disaster of roadway debris flow, through analysis of many debris flow accident roadway records both at home and abroad, to generalize their happening conditions and general characteristics.In fact,the roadway debris flow is the result of sudden unstable failure of the comprehensive function of fault structure,hydraulic water dashing rock gravitation and unjust construction opera- tion in a large rock body,analysed in detail the forming process and thus put forward some concrete measures for preventing the roadway from debris flow.
