| Abstract: | According to the reliability calculation method for structure system and the principle of structure safety classification, the relationship between safety classification of hydraulic structure component and calculated reliability is analyzed. On this basis, the evaluation methods for safety classification of existing hydraulic structure system are studied. As a result, a simple and practical evaluation method for structure safety is put forward. Following the basic principle of Analytic Hierarchy Process(AHP), the reliability evaluation method for complicated engineering system of existing hydraulic structure is further studied. The feasibility of the evaluation method is verified by numerical analysis of examples. |
