中文摘要：

多闸门联合调度是在实际河道、水渠中经常采用的一种控制水量或水位的运行方式,对此进行数值模拟也成为人们关心的问题之一。本文利用闸孔出流公式耦合水流运动平面二维ADI算法,建立了多闸门联合调度的平面二维数学模型。模型被应用到北京市卢沟桥分洪枢纽多闸门联合调度控制洪水的研究之中,并提出了洪水过程中洪峰流量小于2500m^3/s的调度方案,对海河水利委员会批准的调度方案进行了完善和补充,表明该模型可以应用到工程实际之中。

英文摘要：

The use of lock gates to control hydrologic flows is a key strategy in flood control projects. Many investigators have used numerical simulation to study the effect of lock gates on water flows. In this paper,we apply the strobe outflow formula in conjunction with the 2-D flow ADI numerical scheme to establish a two dimensional numerical model of flows enhanced by lock gates. The model is applied to the flood control project at Lugouqiao on the Yongding River in Beijing. It proposes operation schemes for flood control with peak discharge less than 2500m^3/s,which supplements the ones approved by the HWCC. It shows that the model can be accurately applied to working flood control projects.
