摘要为研究岩溶隧道层状节理隔水岩柱水压致裂特性,建立隔水岩柱分析模型,通过量纲分析获得影响隔水岩柱临界承载水压的关键因素,并开展单一节理单元岩体的强度特性分析,借助连续-非连续数值模拟方法(continuum discontinuum element method,CDEM)观察裂缝扩展贯通过程,获得不同节理倾角隔水岩柱的破坏模式和临界承载水压,以及隔水岩柱的破裂度和损伤度随节理倾角的演化规律。计算结果表明:层状节理隔水岩柱的破坏模式包括基岩破坏、沿节理面的层间破坏和复合型破坏;受上覆岩层自重影响,隔水岩柱临界水压具有明显的倾角效应,呈先减小后增大的变化趋势;节理面层间贯穿性破坏的破裂度和损伤度远小于基岩贯穿性破坏。

Abstract: In order to study the hydraulic fracturing characteristics of water resisting rock mass with layered joints in karst tunnels, an analysis model of water resisting rock mass was established, the key factors affecting the critical hydraulic pressure of rock column was obtained through dimensional analysis, and the rock strength properties of single joint element was analyzed. With the help of continuum-discontinuum element method to observe the fracture crack and penetration process,the failure mode and critical water pressure of the water resisting rock mass with different joint inclination angles were obtained, as well as the evolution law of the rock mass fracture degree and damage degree. The numerical results showed that the failure modes of water resisting rock mass with layered jointed included bedrock failure, interlayer failure and composite failure; influenced by the weight of overlying strata, the critical water pressure of water resisting rock column had an obvious obliquity effect, which first decreased and then increased; the fracture degree and damage degree of interlayer penetrating failure were much less than that of bedrock penetrating failure.

Key words: layered joint karst tunnel failure mode continuum-discontinuum water inrush
