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。
January 21, 2006 The largest super burst (surge) water in the history of railway construction in China occurred on January 21, 2006. The instantaneous water flow exceeded 200 m3 / s and the total water inflow exceeded 1 million m3. Thereafter, Again water repeatedly. On the basis of summarizing many large-scale karst water inrush in the Maluoguan tunnel, the basic characteristics of the karst water inrush were analyzed, and the super krill water was defined as "karst water Water karst geological law, put forward the geological cause of deep karst tunnel collapse disaster. On the basis of this, through further analysis of stability mechanics of surrounding rock, the geological factors that should pay special attention to tunnel construction in the high risk area of karst collapse are put forward and the methods of engineering treatment are taken.
