北京營造擋水閘門(天水牌)試驗力學分析
Hydrostatic pressure distribution of the waterproof gate after water storage is shown in Figure 1. Assuming that the water depth is H and any depth below the water surface is represented by point A with a water depth of h, the water pressure at any depth is represented by γh, where γ is the unit. 體積之水重量,即每立方公尺有一噸水重或1000 (kgw/m3)。

因此,本試驗最高水深為2公尺的條件下,其底部所承受的水壓PH為
 
PH=γH
=1000x2
=2000(kgw/m2)=2(ton/m2)
 
整體擋水閘門(寬度為B)所承受水的總作用力F為
F=(γH2B)/2
=(1000x22x3.96)/2
=7920(kgw)=7.92(ton)
 
B (m) :擋水閘門寬度
F (kgw) :水壓作用於擋水閘門上的總作用力
h (m) :由水面往下任一地點之深度
H (m) :蓄水水深
PH (kgw/m2) :擋水閘門底部所受到之靜水壓力
kgw/m3 :單位體積之水重量
