以某工程圆形窗口式井—管排水系统为例,通过理论计算和水工模型试验比较,分析窗口式井—管排水系统的泄流特征及规律。理论计算可以较准确地定量描述该系统的自由泄流流态,较难定量描述其压力流流态,需要根据模型试验进行修正;对于该系统的半压力流流态,很难通过理论计算定性和定量描述。
Taking a circular window type well-pipe drainage system of a project as an example, the discharge characteristics and regularities of the window-type well-pipe drainage system are analyzed through theoretical calculations and hydraulic model tests. The theoretical calculation can describe the free flow pattern of the system more accurately and quantitatively, and it is difficult to quantitatively describe the flow pattern of the pressure flow, which needs to be corrected according to the model test. For the semi-pressure flow pattern of the system, it is difficult to be qualitatively determined by theoretical calculation And quantitative description.
