大规模建造高水头的水利枢纽时,在泄放大单宽流量情况下,必须保证可靠的上下游衔接和消能。此时如果挑流消能方式不适宜,那么采用大家熟悉的消力槛和消力池进行消能方式的可能性就增加了。当空间条件对上下游衔接没有重大影响时(即属平面问题),对这种消能设备曾进行过相当详尽的研究,它们的水力计算方法是以大量系统的研究为基础的,因而是非常可靠的[见参考文献1—3]。对具有上述消能设备的护坦和海漫底板所受水动力荷
Large-scale construction of high-head hydraulic complex, in the discharge of large single-wide flow conditions, must ensure reliable upstream and downstream convergence and energy dissipation. At this point if the flow of energy dissipation is not appropriate, then use the familiar wall and the consumption of energy dissipation tank the possibility of energy consumption increases. While space conditions have had no significant effect on the convergence between upstream and downstream (ie, plane problems), considerable elaboration has been made on such energy-dissipating devices and their hydraulic calculations are based on a large body of systematic research and are therefore very much Reliable [see References 1-3]. On the tank with the above-mentioned energy-saving equipment and the sea flood fan suffered hydrodynamic load
