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.
利用此裝置和物理模型,通過試騐研究得出了底板塊下表麪的壓強隨止水破壞程度和敭壓力水平的變化槼律,提出了敭壓力和縫隙動水壓強的相互作用機理。
