一、前言为了保証水工建筑物的安全,在泄水建筑物的下游通常要修建消能設备。当泄水建筑物上下游的水头差不很大时,有时采用修建靜水墙形成靜水池的办法来进行消能。在靜水墙被下游水深淹沒的情况下,确定靜水墙高度的計算任务是相当繁重的。为了减輕計算上的負担,目前有一些图解法和表解法。比較容易看到的有水力学专門教程或水工手册上的图解和清华大学水利系編写的水力学上的图解。上述图解在相当的程度上簡化了計算。但是,前者在应用时需要作較多的輔助計算,还不甚簡便,后者曲綫根数較少 I. Preface In order to ensure the safety of hydraulic structures, energy dissipation devices are usually built downstream of the discharged structures. When the discharge headwaters upstream and downstream of the difference is not large, and sometimes the use of static water tank to form a static water tank to create a way to dissipate energy. In the case of the hydrostatic wall being submerged in the downstream, the computational task of determining the height of the hydrostatic wall is rather heavy. In order to reduce the computational burden, there are currently some graphical and table solutions. Easier to see there is a hydraulics tutorial or manual on the graphic and Tsinghua University Department of Hydraulic prepared hydraulics diagram. The above diagram simplifies the calculation to a considerable extent. However, the former needs more auxiliary calculations in application, which is not very simple. The latter has fewer curves
