as for construction technology and management characteristics of road and bridge construction, this paper constructs evaluation index system on safety risk of road and bridge construction, this system mainly includes 2 levels such as risk element level and risk factor, effect of each factor presents network structure. On this base, this paper applies network analysis method theory to establish risk evaluation model and method on road and bridge construction safety, it also applies fuzzy comprehensive judgment method and combines with Xinhua viaduct construction case of Guangqing expressway reconstruction and expansion project to illustrate application of this method and calculate construction safety risk grade, which can provide base for risk management, the obtained conclusion conforms to objective reality of project.
