中文摘要：
针对水库安全风险分析问题,分析了影响大坝安全的内外部复杂因素,以不同工况下的洪水条件为前提,综合考虑泄洪能力、蓄水能力、坝体渗漏、运行管理等方面的约束关系,建立了多因素作用下大坝安全响应的结构图仿真模型,提出了面向结构图的大坝安全风险数值仿真分析方法。工程实例应用表明,该方法建模过程便捷,仿真计算与数据可视化分析能有效地耦合,仿真分析结果符合客观实际,为分析复杂因素条件下大坝安全风险分析问题提供了新的方法。
英文摘要：
Aiming at the dam safety risk analysis,a new solution scheme is presented. Firstly,the complex constraint relationship among internal and external influence factors to reservoir safety was analyzed. Based on the different operation conditions,some main factors were considered such as flood-carrying capacity,water holding capacity,dam seepage and operation management. Secondly,a general block diagram-oriented simulation model for the dam safety system under multi-factors was set up. Then,a corresponding numerical simulation method and platform were developed. The method was applied to a practical hydraulic project. The result shows that the modeling process is convenient. The computation and the visual analysis can be coupled effectively,and the results conform to practical state.
