| 摘 要： | 对隧道施工塌方采用模糊层次综合评判法进行风险评估,通过收集和整理隧道塌方的资料,总结影响隧道塌方的因素,再遴选出主要的因素作为模糊层次评估方法的影响因子,然后统计分析得到各个因子与塌方发生概率、塌方量之间的隶属函数,并采用综合赋权法确定评价指标的权重,从而建立塌方风险模糊层次评估模型.该模型在青山岗隧道得到了验证,其分析结果可信.

| Abstract: | Fuzzy analytic hierarchy process (FAHP) of risk assessment has been used in tunnel collapse; through collecting and collating information of the tunnel collapse, the major factors are summed up and selected as the impact factor of FAHP. Through analyzing the statistical materials, the membership function is proposed between the factors and the probability of occurrence of collapse and collapse volume. And a comprehensive assigning method is adopted to determine the weight of evaluation indices. Then the model of FAHP has been established and applied to Qingshangang Tunnel. The results are credible. |
