岩溶山区隧道工程地下水渗漏引起的环境负效应评价指标体系初建

摘要

When tunnels are constructed in karst area,leakage of underground water caused by tunnel construction will usually destroy ecological environment on earth surface.In accordance with conditions including environmental features and tunnel features in the area of tunnel site,this paper selects the relevant indices and adopts the analytic hierarchy process to determine the weights of all indices,and finally establishes the evaluation index system for negative environmental effect caused by leakage of underground water in tunnel projects in karst mountainous area.The system can be used to evaluate the degree of negative environmental effect caused by leakage of underground water during construction of tunnels in karst area.%在岩溶地区修建隧道时，隧道施工引起的地下水渗漏通常会破坏地表生态环境。根据隧址区环境特征和隧道特征等条件，选取相关指标并采用层次分析方法确定各指标权重后，最终建立岩溶山区隧道工程地下水渗漏引起的环境负效应评价指标体系。该体系可用于评价岩溶地区隧道施工过程中地下水渗漏引起的环境负效应程度。
