平原水库多效应耦合优化设计

Multi-effect Coupling Optimization Design of the Plain Reservoir

引入"安全可靠、生态优先、经济最优"的概念设计原则,以水库设计水位、土体性质、计算风速、边坡粗糙率、年蒸发量和生态目标等级等因素为变量,单位立方米供水成本最低为目标函数,水库安全和生态友好为约束条件,建立面向安全、生态、经济多效应耦合的平原水库优化设计模型。并采用遗传算法计算出了双王城水库的优化参数,对围坝形式和防渗形式对单位立方米供水成本的影响进行了比较,结果表明:多效应耦合的平原水库优化模型具有良好的收敛性和全局寻优能力,且在最优设计工况下正方形围坝供水成本比圆形围坝供水成本低,库底铺膜防渗形式造价较高。
