摘　　要：针对利用交汇井液位计算出流量的需求,通过分析交汇井液位及其进出流量之间的关系,提出单井法计算模型;通过分析相邻两座排水交汇井液位和二者之间管道流量之间的关系,提出双井法计算模型。根据模型的边界条件,指出两种方法的适用条件及测试仪器需求。在TC交汇井案例中,根据实际情况,采用双井法建立计算模型,得出相邻两座交汇井液位差与二者之间管道流量的数学关系。According to the flux requirements calculated by the water level of intersection well in drainage system,two methods are proposed,Single-well Model,which was drawn from the relationship analysis between the water level of intersection well and the inlet and outlet flows;Double-well Model,which was drawn from the relationship between water level of adjacent intersection wells and the flux of pipeline between them.The application environment was pointed out according to the boundary conditions and the instruments requirement.In the TC intersection well case,the Double-well Model was applicable practically,and the mathematical relationship was built by the adjacent intersection wells and their inner pipelines.
