摘　　要：为研究明渠梯形断面消力池池深和尾坎高度的计算方法,依据前人对梯形断面消力池水跃共轭水深、梯形断面量水堰(槛)的研究成果,采用能量方程研究梯形断面挖深式消力池、消力坎式消力池和综合式消力池深度和坎高的计算方法。给出了梯形断面消力池池深、尾坎高度的计算公式,通过算例说明了计算过程。提出的消力池深度、坎高的计算公式可以作为梯形断面消力池设计的参考。In order to explore the calculation methods of stilling basin depth and end sill height,we summarize previous research results about conjugate depth of hydraulic jump in trapezoidal stilling basin and measuring weir（ sill）of trapezoidal cross section. According to energy equation,we present the calculation methods of stilling basin depth and sill height with trapezoidal cross section for 3 types of stilling basin,namely,deepened style,baffle wall style,and comprehensive style. On the basis of this,we put forward calculation formulas of stilling basin depth and sill height and exhibit the calculation process through examples. Finally,the calculation formulas can be taken as a reference for the design of trapezoidal stilling basins.
