| 中文摘要: |
| 根据结构体系可靠度计算方法、结构安全性等级评估和划分思路，对水工结构中的构件安全分级与计算安全度之间的关系进行了分析。在此基础上，对现有水工结构系统安全性的分级评估方法进行研究，提出了一个比较简单和实用的安全性评估方法，并根据层次分析法的评估思路，研究了复杂水工结构工程系统的可靠性评估方法。通过数值计算和实例分析，验证了评估方法是可行的，而且比较简单和实用。 |

| 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. |
