摘　　要：以瞬变流模型和随机信号理论为基础，在乌江构皮滩模型的水垫塘边墙上布置了五个测点，运用上举力量测仪量测板块所受的上举力．实验前对仪器进行了动态标定．量测了校核、设计、正常高水位下表孔单泄、表中孔联合泄洪共６种工况下衬砌块上的脉动上举力，得出相应的两个回归经验公式，为边墙衬砌块的设计提供了科学依据．Based on the model for transient flow and the theory of stochastic signals,five measuring points are set along the slope linings of the pool of the Goupitan model.Before the experiment much attention was paid on the dynamic calibration of the apparatus.Under six different kinds of running conditions,the uplift acting on each model block is measured.Two empirical equations are given,which provide a reliable basis for the designing of slope linings.
