为了降低开挖造价,同时保证在高水头的工作状况下无气蚀现象发生,提出了一种新型的掺气消力池。现将在两条开敞式溢洪道上进行的模型试验综述如下:本文所提出的消力池(见图1)有一个掺气阶梯,一个斜坡,二排消力块,尾端还联接一个分布式堰,按不同流量要求渲泄尾水。这样设置的目的,是为了保证泄洪水跃在斜坡末端与第一排消力块之间产生。斜坡和消力块增进了水流稳定状况。水流的掺气,避免了气蚀现象的发生。利用下游分布式堰保 In order to reduce the cost of excavation, and at the same time to ensure that no cavitation occurs under high head working conditions, a new aerated tank is proposed. The model tests now carried out on two open spillways are summarized as follows: The trough proposed in this paper (see Figure 1) has an aerated ladder, a ramp and two rows of blocks, and the tail ends are also connected to a distribution Weir, according to the different flow requirements of the release of tail water. The purpose of this setting is to ensure that flood discharge jumps between the end of the ramp and the first row of power blocks. Slopes and power blocks improve water flow stability. The aeration of the water flow avoids cavitation. Use downstream distributed weir protection
