芦山“4·20”地震公路交通系统震害调查分析
|
摘要
首先调查了芦山"4·20"地震后灾区内公路交通系统的地震破坏情况,总结了道路和桥梁的典型破坏特征,并对其破坏成因进行了分析,指出影响交通系统破坏的主要因素,最后结合调查数据和震害分析结果,对芦山地震中交通系统的总体破坏情况进行了评述,为加深对公路交通系统地震破坏特征的认识、掌握震害影响因素以及开展震后恢复重建工作提供参考。
In this paper,the earthquake damage information of highway system was investigated for the Lushan "4.20"earthquake.The main damage characteristics of roads and bridges in the highway system were summarized based on the investigated data,and the contributing factor of typical damage was discussed deeply to find out the dominant factors which affect the damage level.At last a general seismic damage situation of highway system in Lushan "4.20" earthquake was reviewed based on the investigated data.The conclusion can be used to deeply understand the damage mechanism,grasp the influence factor for each damage mode and develop the rebuilding work of highway system after earthquake.
