重庆市隧道工程地质环境负效应评价体系

以重庆市隧道工程建设过程中日益凸显的地质环境问题为研究对象，运用层次分析法和专家打分法，通过遴选指标、确定权重构建了综合评价模型，并对重庆市绕城高速玉峰山隧道进行了地质环境负效应评价。根据综合评价分级标准，将玉峰山隧道地质环境负效应分为4个等级，分别为严重区、较严重区、中等区、较轻区。通过调查验证，评价结果与实际情况一致性较好。研究为该评价方法的推广应用奠定了基础。

System for Evaluating Geological Environment Negative Effect in Chongqing Tunnel Engineering Construction Process

The geological environment problems which become increasingly prominent in Chongqing tunnel engineer -ing construction process are taken as research objects in this paper .Applying methods of anlaytic hierarchy and sco-ring by experts ,we establish a comprehensive evaluation model by selecting indices and determining the weights of indices.Then, we evaluate the geological environmental negative effect of Yufengshan tunnel of highway -ring a-round Chongqing;according to the comprehensive evaluation grading standard , we divide the negative effect area into four grades , which are serious area , relatively serious area , medium area and relatively minor area .Through investigation and verification , we found that the evaluation results are basically in accordance with actual situation and the study lays a foundation for the popularization and application of the evaluation method .
