中山市交通系统地震易损性分析

交通系统地震易损性分析主要是针对系统中的道路、桥梁及路边建筑破坏的影响。分别采用经验统计法、单体桥梁分析方法、瓦砾堆积物计算方法得到了各自对应的道路路段通行概率,而这三个因素共同构成了道路路段的最终通行概率,通过Monte-Carlo算法即可得出交通系统连通可靠性。根据分析结果寻找薄弱环节,为制定相应的防震减灾对策提供依据。

Seismic Vulnerability Analysis of Transportation System of Zhongshan City

The paper analyzed seismic vulnerability of roads and bridges consider ing the effect of roadside buildings.The paper jointly used the statistical emp iric formula method,single bridge analysis method and debris piling method to g et the corresponding road sections＇ access probability respectively.The three f actors formed the final access probability of road sections.By the Monte-Carlo algorithm,the paper obtained the connectivity and reliability of transportation system.Based on the results,the analysis of weak links can provide the refere nce for drawing up the corresponding earthquake disaster mitigation measures.
