【摘要】 本文从历史震害经验出发,分析了震后城市内部道路通行性的影响因素,提出了路段通行概率的计算公式;在此基础上,建立了用蒙特卡罗模拟方法分析路网连通性的仿真模型,最后用实例验证了这一分析方法的实用性。更多还原

【Abstract】 Based on the study of historical earthquake cases,the factors which have influence on the accessibility of a urban transportation system are summarized.The calculation formula is put for- ward to determine the function of a single road.Then.the simulation model for the evaluation of a post-earthquake city’s inner road network is set up.Finally an example is given to show the va- lidity of this method.更多还原
