河床渗井是近年来国内新发展起来的一种大口井。河床渗井具有出水量大、水质好、工程造价低和运行费用省等优点。对中小城镇和工矿企业的给水工程,这种井的经济效益尤为显著。用流网法解平面势流问题,这是大家所熟知的。但用流网法解空间势流问题,还没有先例。本文对具有对称轴的空间势流问题采用流网法求解,解决了河床渗井的出水量和影响半径两大难题。实践证明,这种计算方法是切实可行的。
Infiltration of riverbeds is a large-scale well developed in China in recent years. Riverbed seepage wells have the advantages of large water output, good water quality, low construction cost, and low operating cost. For the water supply projects of small and medium-sized towns and industrial and mining enterprises, the economic benefits of such wells are particularly significant. The flow network method is used to solve the plane potential flow problem, which is well known to everyone. However, there is no precedent for using the flow network method to solve the problem of spatial momentum. This paper uses the flow net method to solve the problem of space potential flow with symmetry axis, which solves the two major problems of the water inflow and the radius of influence of the infiltration well in the riverbed. Practice has proved that this calculation method is feasible.
