1.定义作用于坝等水工建筑物的底面以及基础的孔隙或裂缝的任意断面垂直向上内部水压力,可定义为扬压力。另外,若以护岸建筑物的沉箱和砌块等为对象,作用于设置在水中的沉箱和砌块底面的向上波浪压力所形成的静水压力和动水压力,也可定义为扬压力。 1. Define the vertical internal hydraulic pressure acting on the bottom surface of hydraulic structures such as dam and any section of the foundation’s pores or crevices, which can be defined as the uplift pressure. In addition, hydrostatic pressure and hydrodynamic pressure formed by the upward wave pressure acting on the caisson provided in the water and the bottom surface of the block may also be defined as the raising pressure, for the caisson and blocks of the bank revetment.
