摘要
针对山地城市的路网结构特殊性,根据山地城市路网模型,提出了山地城市道路的连通率的计算方法,然后基于蒙特卡罗的模拟算法对震后路网可靠指标进行评估,并对山城重庆某局域路网进行了震后路网可靠性评估,分析评估结果为应急救护中心的选址提供依据.
Based on mountain city road network and special structure of urban road network model. Calculation of mountain city road connectivity rate is proposed. Based on Monte Carlo simulation algorithms,reliable indicator of road network after earthquake is evaluated,and an assessment of road network reliability evaluation of a local road network in Chongqing after earthquake is conducted. Results of the analysis and evaluation provide basis for the siting of the emergency rescue center.
