摘要
阐述了灾时山区路网各路段组成单元通行概率的分析方法,采用Monte Carlo模拟法对山区路网连通可靠度进行分析和计算,并通过概率解析法来检验Monte Carlo模拟法的计算精度。采用Monte Carlo模拟法分析路网节点间连通可靠度,提出了灾时山区路网应急救护中心优化选址方法。最后,通过实例阐述其计算过程。结果表明:采用Monte Carlo模拟法分析山区路网交通节点间的连通可靠度,找出灾时山区路网连通薄弱环节,为山区应急救护中心优化选址提供依据。
Some analysis methods for the access probability of the mountainous road network component units were illuminated when disasters occurred.Monte Carlo simulation was applied to analyzing and calculating mountainous road network connectivity reliability.The calculation precision of Monte Carlo simulation was tested by probability analytic method.A optimization means for selecting the location of the emergency rescue center was provided by Monte Carlo simulation.Finally,calculated process was illustrated through numerical example.Results showed that some weak links of mountainous road network for connectivity could be obtained by Monte Carlo simulation.Selecting the optimum location for the emergency rescue center was of significance when disasters occurred.
