摘要

摘要: 为了将岩溶涌水评判系统中定性描述的影响因子定量或半定量化，以便直观、有效地对隧道地质灾害进行预测预报，本文采用层次分析技术(AHP)将隧道岩溶涌水的多因素量化集成，并导出评判隧道岩溶涌水的综合指标（Skarst），用于评判不同岩溶水文地质条件下隧道涌水的风险性。应用该模型对乌池坝隧道岩溶涌水进行评价，结果为： ZK259+890～ZK258+500段和ZK255+405～ZK253+182段属低风险区段，Skarst≤0.24；ZK256+300～ZK255+405段和ZK258+500～ZK257+500段为中等风险区段，0.24＜Skarst≤0.70；ZK257+500～ZK256+300段为高风险区段，Skarst＞0.70。

Abstract: For the purpose of quantitative and semiquantitative description of impacting factors of the evaluating system for karst tunnel gushing, which will help us to predict the geological disasters directly and effectively, the paper has adopted Analytic Hierarchy Process (AHP) to quantitatively integrate multi-factors of tunnel gushing, with synthetic index (Skarst) for judging karst tunnel gushing being concluded, which will be used to evaluate the risk for tunnel gushing under different karst hydrogeological conditions. A case study of tunnel gushing by applying AHP has been operated in Wuchiba, and we have concluded the results as follows: the sections of ZK259+890～ZK258+500 and ZK255+405～ZK253+182 are the places with low risk for tunnel gushing, whose Skarst is lower than 0.24 (including 0.24); the sections of ZK256+300～ZK255+405 and ZK258+500～ZK257+500 are the places with middle-class risk for tunnel gushing, whose Skarst is in the range of 0.24～0.70(excluding 0.24, but including 0.70); the sections of ZK257+500～ZK256+300 is the place with high risk for tunnel gushing, whose Skarst is higher than 0.70 (excluding 0.70).
