Risk Analysis of Dams during Construction Based on Catastrophe Evaluation Method

摘要

To address the accident-prone problem of dams during construction,the difficulty of supervise and control construction goals such as safety,quality,process,costs,etc.,and the adverse effect that traditional risk assessment would cause when determine the weight of risk factors subjectively,this article,based on the establishment of comprehensive evaluation index system of dams during construction,the calculation of each goal and the comprehensive goal of value at risk using the catastrophe evaluation method,is to achieve the objective of comprehensive evaluation.Through applying the method to risk evaluation of the construction program of Yanshan Reservoir,the author verifies rationality of the method,which preferably offers instructions to engineering construction.
