Abstract: Disclosed is a sewage pipe network hydraulic model building method based on three-dimensional geographic information. According to the method, physical corresponding relation between each manhole node of the sewage pipe network and surrounding buildings is obtained through the three-dimensional geographic information, the population of the sewage pipe network is estimated as prior information according to the corresponding relation, an optimization algorithm is used to determine the total influent time series of all manhole nodes in a region based on the population proportion, and flow fluctuation coefficient for each manhole node is optimized and calculated, such that the influent time series of each manhole node is determined, and the sewage pipe network hydraulic model is built accurately. The present disclosure further provides a method that uses the population data to replace the pipe length/catchment area data as the prior information for sewage pipe network flow check.
