英文摘要：

By taking the stormwater pipe operation parameters as constraint conditions and using the stormwater pipe section depth to build system state transition equation, we establish the mathematical model for stormwater pipe sys- tem and study the optimal service radius of stormwater pump station. We use the dynamic programming method to solve the optimal model and carry out a case study. The results show that the application of dynamic programming method for solving the optimal service radius could achieve global optimization in stormwater system. Combined with the maximum allowable depths in different regions of China, we calculate the corresponding optimal service radius of storm water pump station which can provide a reference for improving the planning of stormwater system.
