摘要
在岩溶区隧道建设的过程中,突水突泥灾害频繁发生,对工程建设造成巨大的安全隐患和经济损失。以马口排隧道为工程依托,采用理论分析与工程实际相结合的技术手段,分析了引发突水突泥灾害的关键性影响因子,并对各影响因子进行二级指标划分,提出层次分析法与加权平均法相结合的岩溶隧道突水突泥风险评估模型,得到相应结论。
During the process of tunnel construction in karst area,the sudden occurrence of waterlogging and flooding occurred frequently,which caused huge safety and economic losses to the project construction. Based on the technical analysis of the combination of theoretical analysis and engineering practice,this paper analyzes the key influencing factors of the sudden flooding and muddy disaster,and divides the two factors into the index,and puts forward the method of analytic hierarchy process. Based on the statistical and analytic hierarchy process,the risk assessment index system of water bursting is established,and the geological structure and engineering influence are determined by weight analysis.
