摘　　要：本文基于波浪理论,通过水工模型不同尾坎坡度条件下常规式消力池和跌坎式消力池的波浪特性的研究,结果表明:消力池平均波高随尾坎坡度的增大而减小,尾坎坡度对跌坎式消力池波高的影响更大,但平均周期与尾坎坡度没有呈现出明显的规律;通过对试验数据的分析,得到了不同特征波高间的换算关系,得出了常规式消力池和跌坎式消力池的相对特征波高H1/100/h2的经验计算式;同时还发现出池波浪特性σw/h2与尾坎坡度i存在较好的线性关系。Based on the wave theory,the wave characteristics of the conventional stilling basin and the stilling basin with drop sill under different end slopes are studied in this paper through hydraulic model tests.The results show that the average wave height of stilling basin decreases with the increase of the end slope,and the end slope has a greater impact on the wave height of the stilling basin with drop sill,but there is no obvious rule between the average period and the end slope.The conversion relationship among the different characteristic wave heights and empirical formulas of the relative characteristic wave height H1/100/h2 of the conventional stilling basin and stilling basin with drop sill are obtained by the analysis of test data.In addition,there is a linear relationship between the wave characteristicσw/h2 and the end slope i.
