【摘要】 运用整体风险分析法对隧道工程在地震荷载作用下的易损性进行评估。首先通过层次分析法进行隧道易损性因子筛选,然后运用概率统计方法进行处理,计算出地震荷载作用下易损性的权重组合值,从而绘出隧道的风险评估图,最后使用地震实例中收集到的隧道震害资料对该模型进行验证。研究表明,运用整体风险分析法评估复杂、多变的隧道易损性问题是完全可行的。更多还原

【Abstract】 Assessment is made on the vulnerability of the tunnels to the earthquake loads based on the holistic risk analysis approach.In the paper,a risk assessment model is firstly established by using the analytical hierarchy process as a screening tool and then process is made by means of probability statistics method so as to obtain the comprehensive weight values of the vulnerability of the tunnels to the earthquake loads and achieve the risk assessment diagram of the tunnels.A preliminary verification of the proposed model is conducted by comparing the prediction results with the data collected in the earthquake cases.The study indicates that it is completely feasible to use the holistic risk analysis approach to assess the complex and variable issue of the vulnerability of the tunnels.更多还原
