| 摘 要： | 基于结构可靠度指标的物理含义,建立了水库泄洪风险计算优化模型,并引进了粒子群全局优化算法对该模型进行求解.通过对该模型在具体水库泄洪风险计算的应用举例,表明了该水库泄洪风险计算理论不仅能有效地避免求偏导运算,且能获得高精度的运算结果,求解速度也有一定的优势.

| Abstract: | The risk analysis of reservoir flood discharging as an important research subject has been focused on widely by hydraulic engineering people during past days.Based on the physical meanings of structural reliability index,the optimization model of flood discharging risk is established in this paper,and the global PSO is introduced to solve the model.Combining with the listed computation example on flood discharging risk of reservoir,it is showed that Partial difference operation can not only be avoided effectively by means of the theory,but also the better solution and a quick operation speed can also be gained in the way. |
