等宽矩形断面挖深式消力池深度计算方法研究

Calculation method research of the depth of deepened-stilling basin with full-width rectangular section

为计算等宽矩形断面挖深式消力池深度,构造以收缩断面水深为横坐标,消力池深度为纵坐标的函数。作出相应函数的两条曲线,其交点的横坐标即为收缩断面水深。对曲线进行离散化,推导了收缩断面水深的表达式,进而推求出消力池深度及跃后水深。

In order to calculate the depth of deepened-stilling basin with full-width rectangular section,the function with contractional depth as horizontal coordinate and depth of stilling basin as vertical coordinate is constructed.The horizontal coordinate of the intersection of corresponding function curves is the contractional depth.The expression of contractional depth is derived after the curves are discretized,and then the depth of stilling basin and sequent depth and can be calculated.
