这里推荐一种掺气消力池,这种消力池可减少整个工程的开挖量,并且运用时不存在气蚀问题.下面介绍其在两个明槽溢洪道上所进行的模型试验.由于水工建筑物投资大,且现代技术不断更新,促使工程师日益需要选择投资少,并适应新技术发展的工程设计方案.这里所介绍的消力池(如图1),它包括有掺气坎、斜坡段、两排消力墩和末端的复合堰(用以控制各级流量下的下游所要求的尾水水位).这种布置,其作用为水跃在斜坡段末端和第一排消力墩中间产生.斜坡
Here, we recommend an aerated tank, which can reduce the excavation volume of the whole project, and there is no cavitation problem when it is used.The following describes the model tests carried out on two open channel spillways. Large investment in hydraulic structures, and the continuous upgrading of modern technology, prompting engineers increasingly need to choose less investment, and adapt to the development of new technology engineering design. Described here as the power pool (Figure 1), which includes aerated ridge , A ramp section, two rows of weak piers and a composite weir at the end (to control downstream tail water level required at all levels of flow) This arrangement has the effect of hydraulically jumping at the end of the ramp section and the first row The middle of the force pier
