Abstract

The invention provides a one-two-dimensional hydrodynamic coupling analysis method based on urban surface and underground pipe network, which comprises the following steps: establishing the urban pipenetwork model; the urban pipe network model comprises a runoff generation calculation model, a one-dimensional pipe network model and a two-dimensional coupling model; inputting surface water data and groundwater data, and establishing surface-subsurface connection relationship according to the surface water data and groundwater data; generating and optimizing grid elements; calculating surface runoff and drainage pipe network flow respectively; calculating the exchange water quantity of surface runoff and drainage pipe network flow; and in order to realize the hydrodynamic coupling of two-dimensional underground pipe network on the surface, checking the calculated exchange water quantity. The invention realizes coupling analysis and calculation of surface groundwater flow for urban rainstorm waterlogging.

Description

technical field [0001] The invention relates to the technical field of hydrodynamic analysis, in particular to a one-dimensional and two-dimensional hydrodynamic coupling analysis method based on urban surface and underground pipeline networks. Background technique [0002] As an important tool for flood risk map compilation, flood analysis software has always been dominated by foreign commercial software. Our country is a big water conservancy country, and has achieved world-renowned achievements in many aspects of the water conservancy field, but we have not formed a domestic flood analysis software brand of our own. Mountain torrents and urban floods are still disasters that pose a huge threat to people's lives and property. If it involves its own flood analysis method, it is a technical problem that needs to be solved to achieve reliable analysis of flood. [0003] Although methods such as flood analysis methods based on one-dimensional non-constant numerical models are...
