摘要：

基于我国西南山区修建隧道工程中常会遇到岩溶和不良地质条件,施工中经常出现无法预料的地质灾害,如突水、突泥、坍塌等,造成极大的安全隐患等问题.以湖北沪蓉西高速公路乌池坝隧道为工程背景,通过系统的补充地质调查和地质分析,探讨了隧道的岩溶发育规律,综合考虑岩组岩性、地质构造、地下水位和预计涌水量等因素,对隧道岩溶突水突泥的风险进行了分段评价,初步提出了岩溶隧道四级风险评价体系,在风险分级的基础上,对不同风险段超前地质预报方案进行了设计,并根据预报情况制定灾害防治措施,该研究对于高风险岩溶隧道的灾害防治具有一定的意义.

Abstract:

During tunnel construction in the mountains of southwest China, karst and unfavorable geological conditions often occur. Tunnel construction often encounters unforeseen disasters, such as water inrush, bursting mud, and collapse which cause great hidden troubles to safety. Taking the Wuchiba Tunnel as an example, through applying the supplement geology survey and geology analysis, the karst development was discussed. In the risk evaluation of dangerous parts along the tunnel, the factors such as formation lithology, geological structure, underground water level, and the forecasted discharge were synthetically considered. The risk evaluation system with 4 ranks about karst tunnels was put forth. Based on the risk rank, the advanced forecasting program was designed for the different parts with different ranks, and the disaster prevention measures can be made with the predictable results. The study has great significance for disaster prevention of karst tunnels.

Key words: karst tunnel; water inrush and mud outburst; risk evaluation; geology forecast; disaster prevention
