基于模糊层次分析法的隧道坍塌风险评估

摘要

以重安江隧道为工程背景，以模糊层次分析法建立风险评估模型。在模型建立过程中，基于国内隧道坍塌事故原因的统计分析及隧道自身情况，确定风险因素。根据类似工程中的统计数据，结合工程实际情况，利用相对标度法确定各因素的权重值。将所得模型应用于实际隧道中，获得不同里程段隧道坍塌事故发生的可能性。%Based on Chonganjiang road tunnel,fuzzy analytic hierarchy process is used to establish risk evaluation model on tunnel collapse.In the process of mode,risk factors are evaluated,based on sta-tistical analysis on tunnel collapses in china,and on the characters of Chonganjiang tunnel.Combined with similar proj ects and engineering situation,relative scale methodology is used to obtain weight value on risk factors.The model is used in Chonganjiang tunnel to obtain the possibility of tunnel col-lapse in mileage segments.
