随着道路网络的日趋复杂化,传统的对单条道路进行可靠度分析的方法已经不能客观反映道路及其网络的可靠度特性,必须计入网络中各道路的相互影响。该文将道路网络可靠度与道路结构可靠度相结合,建立了道路网络结构可靠度的计算方法。利用软件Mat-lab对道路结构可靠度进行蒙特卡洛分析,再将各道路的结构可靠度代入到网络中分析整个网络的结构可靠度。
With the increasing complexity of road networks, the traditional method of reliability analysis of a single road can no longer objectively reflect the reliability characteristics of roads and their networks, and must be taken into account in the interaction of various roads in the network. This paper combines the reliability of road network with the reliability of road structure, and establishes the calculation method of the reliability of road network structure. Monte-Carlo method is used to analyze the reliability of road structure by software Mat-lab, then the structural reliability of each road is substituted into the network to analyze the structural reliability of the whole network.
