摘要
隧道施工过程常会发生突水涌泥灾害,严重危及隧道开挖安全。准确预测隧道突水风险等级,对预防突水灾害具有重要意义。以青岛四号线静沙区间隧道为工程背景,应用Delphi调查技术选取隧道突水突泥影响因素,通过层次分析法构建多层次隧道突水风险评价体系,结合模糊数学理论对隧道易发突水突泥段作出风险评价。研究结果表明,青岛四号线隧ZDK25+090.9~ZDK25+528段突水涌泥风险等级为IV级,和工程实际情况基本一致。本文研究方法可对相关隧道项目突水涌泥危险评价管理提供参考依据。
The disasters of water gushing and mud outburst often occur during tunnel construction, which seriously endangers the safety of tunnel excavation. It is of great significance for water gushing disasters to accurately predict the risk level of water gushing tunnel. Taking the Jingsha section tunnel of Qingdao Metro Line 4 as the engineering background, Delphi survey technology is applied to select the influencing factors of tunnel water gushing and mud outburst. A multi-level risk evaluation system of tunnel water inrush is formed through the analytic hierarchy process, and the risk evaluation of tunnel water gushing and mud outburst section is made by combining the fuzzy mathematics theory. The results show that the risk level of tunnel ZDK25+090.9~ZDK25+528 of Qingdao Metro Line 4 is at Level IV, which is basically consistent with the actual engineering situation. The research method in the paper can provide a certain basis for the risk assessment and management of related tunnel projects.
