高拱坝施工道路是保证高拱坝工程顺利实施的重要条件之一,由于其所处的环境较为复杂,不确定性因素很多,使得施工道路经常受到损坏。为使施工道路受到损坏后尽快恢复其应有的功能和运输强度,应用复杂网络理论,根据高拱坝施工场地特征,建立了高拱坝场内施工道路网络模型,并采用Leaderrank算法对道路网络的重要节点进行挖掘和验证。最后,运用工程实例,建立了一个具有23个节点的施工道路网络模型,通过对网络模型特征进行分析,并经节点失效验证,发现重要节点排序结果符合高拱坝施工道路实际情况。研究结果可以为高拱坝施工道路管理、抢修提供理论依据。
Abstract
Construction road is a crucial factor to ensuring the construction of high arch dam project; however, construction road is often damaged because of complex environment and uncertain factors. In an attempt to restoring the function and transport intensity of the damaged road as soon as possible, a network model for internal construction road of a high arch dam containing twenty-three nodes is established as case study based on complex network theory in line with the characteristic of high arch dam’s construction site. Leaderrank algorithm is employed for the mining and verification of important nodes of the road network. Node-failure mode verification results demonstrate that the node rank result accords with the actual project. The research could offer theoretical basis for road management and emergency maintenance of construction road for high arch dam.
