城市高架道路系统抗震性能分析
|
摘要
城市高架道路系统是城市交通系统的抗震薄弱环节,其震害不仅影响其自身的通行能力,通常还会影响高架道路下方的地面交通。对高架道路系统抗震性能的分析方法进行了系统阐述。采用系统分析方法对上海市内环高架道路系统进行了抗震性能分析,得到了震后系统通行时间延长值,而震后系统通行时间延长反映了系统通行能力的降低。
The urban elevated line system is a weak link of the urban traffic system in earthquake.The seismic damage of the elevated line bridges will decrease their own transportation capacity and the roads under them.The methods were presented in the paper to analyze the performance of the elevated line system in earthquake.A elevated line system in Shanghai was analyzed with systematic analysis method and passage time delay after earthquake was obtained which reflects decrease of passage capacity of the system.
