本文提出的消力池结构适用于有各种水力参数的无压输水道上下游衔接枢纽。这种结构应用最主要的地方是宽度不受限制,且沿水流冲刷底部不长的下游河段。池的结构是一个普通的矩指池,只是沿池顶水边线设有挡板(图1)。池的轮廓尺寸按下列方法确定。泄水(?)坎边缘上水深为 The structure of the stilling pool proposed in this paper is suitable for the upstream and downstream convergence joints of pressureless waterways with various hydraulic parameters. The main application of this kind of structure is the unrestricted width, and the lower reaches of the river are washed along the water flow at the bottom. The structure of the pool is an ordinary moment finger pool, with baffles just along the waterline at the top of the pool (Figure 1). The outline size of the pool is determined as follows.
