Suitability Evaluation Method of Existing Facilities in Mountain Tunnels Based on IAHP
Accurately assessing the suitability of existing facilities within mountain tunnels is the core of reusing ex-isting tunnels to lay new pipelines.In response to the current lack of evaluation methods for the suitability evaluation of existing facilities in mountain tunnels in China,the improved analytic hierarchy process(IAHP)was introduced into the evaluation process.An evaluation index system for the suitability of existing facilities in mountain tunnels was established,which comprehensively considered factors before and after reuse.Addressing the shortcomings of the nine-point scale method and the three-point scale method,the index scale method was adopted to determine the weight of each index.Combined with quantitative or qualitative evaluation methods for each index,an evaluation method for the suitability of existing facilities in mountain tunnels was proposed.The proposed method was applied to the reuse evaluation of mountain tunnels in practical engineering.The research results indicate that the evaluation results are consistent with the conclusions of actual engineering situations,which verifies the feasibility of the pro-posed evaluation model.
