【Abstract】 A new design way is proposed which takes the overflow well as the dividing line and the combined sewer network with overflow wells is disassembled into a series of smaller complete combined sewer networks. Based on the conjunction matrix and the nodal conjunction characteristics matrix of the combined sewer network, the program takes the nodal mass-conservation equation and nodal recurrence algorithm as the hardcore algorithms to realize the pipeline flow computation and the hydraulic computation of the complete combined sewer networks. This method can effectively reduce the size of the computing model of the pipeline networks and the difficulty of the program design and improve the practicability of the program.更多还原
