摘要
宜万铁路马鹿箐隧道2006年1月21日发生了中国铁路建设史上最大规模的的超级突(涌)水,突水瞬间流量超过200 m3/s,涌水总量大于100万m3,其后又多次突水。在总结马鹿箐隧道多次超大规模岩溶突水的基础上,分析岩溶超级突水的基本特征,并将这种超级突(涌)水定义为"岩溶溃水";通过研究诱发溃水的岩溶地质规律,提出深部岩溶隧道溃水灾害的地质成因。在此基础上,进一步通过围岩稳定性力学机理分析,提出在岩溶溃水高风险的地段进行隧道建设时应特别关注的地质因素及采取工程处治的方法。
The super burst water occurred in Maluqing Tunnel of Yichang-Wanzhou Railway on January 21,2006,which would be the largest burst water in China history of railway construction.The flow rate was more than 200 m3 / s and the total water inflow was more than 100 × 104 m3.This phenomenon occurred again and more than once after that accident.Based on the burst water in Maluqing tunnel,it was analyzed its characteristics.This supper water inflow be defined karst water burst flood.By research on the law of karst geology,the geologic genesis of water burst in deep tunnel can be got.The Mechanical mechanism of stability of surrounding rock was studied.On the basis,tunnel’s geological factors and engineering treatment method was got.
