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.

Key words: high arch dam, roads in construction site, complex network, small world network, leaderrank, important node mining
