目前，对消力池或水垫塘中底板块的脉动压强研究资料居多，对冲坑底部岩块上的脉动上举力研究资料甚少，而对边墙或边坡岩块上脉动上举力的试验研究至今尚为空缺．笔者介绍了水垫塘边墙板块上脉动上举力的量测技术，并通过某工程在1：110比尺水垫塘模型上当坝身泄洪时，对水垫塘边墙板块上的脉动上举力进行实验研究．利用压力计，经A／D转换送入计算机进行数据采集，并经信号分析及数据处理得出边墙板块上沿程的脉动上举力幅值分布规律及频域内的能量分布特性等，为实际工程中水垫塘边墙板块的稳定性设计提供了科学依据．
At present, most of the research materials on the fluctuating pressure in the bottom plate of the stilling pool or the plunge pool are few, and there is little research on the uplift force of the pulsation on the bottom of the hedge pit, The pilot study is still vacant. The author introduced the measuring technique of the pulsating upper lifting force on the water cushion pond wall plate, and through a project on the 1: 110 scale plunge pool model, Emphasis on experimental research. Using pressure gauge, the A / D conversion into the computer for data acquisition, and by signal analysis and data processing edge of the wall plate along the pulsation force amplitude distribution and frequency domain energy distribution characteristics, etc. In the actual project, the design of the stability of the water cushion pond wall plate provides a scientific basis.
