摘要
在分析总结交通系统震害预测中的瓦砾堆积计算等相关问题的基础上,对由瓦砾阻塞计算道路通行概率的方法进行了改进,提出了有效宽度的概念和瓦砾阻塞量密度的计算方法。并以唐山地震中跃进小区和泉州市湖心街路段为实例进行计算,并与已有的方法进行对比,结果表明了改进后方法的合理性。
On the base of analysing and summarizing the correlated problem,such as the debris piling problem in the earthquake damgae forecasting for the transport system,the calculating method for traffic probability of the debris piling problem is improved.And the conception of effective width and the calculating method for debris jam density are proposed.As the same time,we take the Yuejin village in Tangshan and Huxin street in Quanzhou as examples,to calculated the probability by proposed method and comparing with the existing method,and calculated results indicate the superiority of the improved one.
