An Analysis on Key Problems of Safety Assessment of High Risk Operations in Hydroelectric Project

摘要

It is of great necessity to carry out safety assessment of high risk operations in hydroelectric projects. We analyze the key problems of safety assessment of high risk operations. Specifically, a questionnaire can be designed by applying the method of Failure Mode and Effects Analysis (FMEA) firstly; then the factors and consequences of risks in such operations can be generated by the questionnaire and interviews; further, the relationship among those factors can be determined based on statistical analysis, and a comparison matrix of Analytic Network Process can be constructed accordingly to verify and modify the model for safety assessment; finally, based on the outcome of safety assessment, the weak point in the hydroelectric project can be revealed and monitor, so that the safety of the project can be improved.
