水垫塘底板失稳区脉动压力的实验研究

Experimental Investigation of Fluctuating Pressure in the Instability Area of Plunge Pool

本文通过水工模型试验 ,对水垫塘冲击区底板块表面及底面动水动力进行了测量。重点分析了失稳区底板块动水压力特性及相关特性。研究表明 :时均上举力和脉动上举力是造成底板块失稳的主要原因。

On the experimental model, fluctuating pressure on the bottom of plunge pool was measured.Characteristics and correlation of fluctuating pressure in instability area were specially analyzed.The conclusion of investigation is that fluctuating uplift and averaged uplift can give rise to the instability of floor slabs.
