综合考虑影响隧道安全的各主要因素,运用整体风险分析法评估隧道在地震作用下的易损性。使用层次分析法,筛选影响隧道易损性的因子;运用概率统计方法,计算隧道易损性的权重组合值,绘出隧道的风险评估图;通过收集的隧道震害资料对该方法进行验证。结果表明,运用整体风险分析法评估地震作用下隧道的易损性是完全可行的。 Considering the main factors affecting the tunnel safety, the overall risk analysis method is used to evaluate the vulnerability of the tunnel under the earthquake. Using AHP to filter out the factors affecting the vulnerability of the tunnel; using the probability and statistics method to calculate the weight combination value of tunnel vulnerability and drawing a risk assessment of the tunnel; and verifying the method through the collected tunnel damage data. The results show that it is feasible to evaluate the vulnerability of tunnel under earthquake by using the overall risk analysis method.
