Risk Evaluation For Le Shan Power Transmission & Transformation Project

Risk management is the essence of safety management,and establishing a security-risk management system is the focus of building "the three management systems" of safe production for State Grid Corporation,which plays an important role in forming prevention mechanism of safe production and promoting the safety and harmony for enterprises.This dissertation firstly deeply studies the theory of risk management.It elaborates the concepts of risk management of construction projects,and introduces some methods of identifying risk with analyzing their properties,nature and scope of application.Also, it chooses to introduce four methods of evaluating risk:R = P×C risk rating evaluation method,fuzzy comprehensive risk evaluation method,extrapolation and Monte Carlo simulation method.Then the construction risk of Le Shan power transmission & transformation project is studied in this paper with using AHP method to identify its construction risks and major construction risk factors.After applying fuzzy-grey comprehensive risk evaluation method to evaluate its whole construction risk level,it uses R = P×C risk rating evaluation method to analyze each risk level of each risk factor.Finally,it proposes specific strategies for dealing with different risk factors of different risk levels.
