scale of uplift pressure

Transformation law of the pressure acting on the bottom of slab with extent of water-seal inactivation and the scale of uplift pressure is obtained and interaction mechanism of uplift pressure and hydrodynamic pressure is given.
利用此装置和物理模型,通过试验研究得出了底板块下表面的压强随止水破坏程度和扬压力水平的变化规律,提出了扬压力和缝隙动水压强的相互作用机理。
