| 摘 要： | 通过对我国西南地区渝怀铁路圆梁山隧道的分析发现含水结构中储有能量、岩溶水压力对岩体的应力作用、含水结构围岩的稳定性被破坏是隧道突水涌泥发生的必要条件;依据阻水结构性质将岩溶隧道的突水模式划分为防突岩层破坏型与填充介质渗透失稳型2大类。据此提出土石回填、超前小导管支护、注浆加固、加强监控量测等岩溶隧道突水涌泥综合防治措施,可为类似工程建设提供借鉴。

| Abstract: | Through the analysis of Yuanliangshan Tunnel of Chongqing-Huaihua Railway in Southwest China it is found that the storage of energy in the aquifer structure the stress effect of karst water pressure on rock mass and the destruction of the surrounding rock stability of the aquifer structure are the necessary conditions for the occurrence of water and mud gushing in the tunnel.According to the characteristics of water resisting structure the water gushing modes of karst tunnels can be divided into two types including the failure type of outburst prevention stratum and the seepage instability type of filling media.Based on this comprehensive prevention measures for water and mud gushing in karst tunnels were put forward such as earth rock backfilling advance small conduit support grouting reinforcement and strengthening monitoring and measurement which can provide a reference for similar projects. |
