侧槽溢洪道由侧堰、侧槽、(渐变段)、陡槽和消能工等几个部份组成。其中,除侧槽内的水流属沿程增量流,要用不同的方法计算外,侧堰陡槽等的水流均为定量流,计算方法与一般溢洪道相同,唯在使用堰流公式Q=σ_sm_oB(2g)~2(1/2)H_0~(3/2)推算H_o求库水位时,侧堰淹没系数σ_s选择和正堰稍有差异。原因是侧槽中的水面线呈降水曲线,水位对侧堰各点的淹没影响不同。当侧槽首端的水位开始对侧堰发生淹没时,由于全堰的调整作用,堰的流量系数还不会立刻出现降低的现象。只有淹没度达到一定值时,淹没的影响才会表现出来。根据我们的试验成
Side channel spillway from the weir, side slot, (gradient), chute and dissipators and other several parts. In addition, the flow in the side tank is along the incremental flow, to be calculated by different methods, the flow of the side weir chute and other flow are quantitative flow, the calculation method is the same with the general spillway, only using weir flow formula Q = σ_sm_oB ( 2g) ~ 2 (1/2) H_0 ~ (3/2) When we calculate the water level of H_o, the submergence coefficient of side weir σ_s is slightly different from the positive weir. The reason is that the water line in the side tank shows a precipitation curve, and the influence of submergence of the water level on each point of the side weir is different. When the water level at the first end of the side tank begins to submerge the weir, the flow coefficient of the weir will not immediately decrease due to the adjustment of the total weir. Only when the submergence reaches a certain value, the influence of submergence will manifest itself. According to our test into
