Abstract

The invention provides a surface two-dimensional underground pipe network hydrodynamic coupling method based on spatial topology, which comprises the following steps: inputting surface water data andunderground drainage system water flow data, and establishing surface-underground connection relationship according to the surface water data and underground drainage system water flow 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; checking the calculated exchange water quantity to realize the hydrodynamic coupling of two-dimensional underground pipe network on the surface. The invention realizes the division of the unstructured meshof the analyzed area, has a plurality of unstructured mesh division functions, and can realize the discrete arbitrary complex geometric boundary of the unstructured mesh, the cross processing of the boundary, and the optimization of the mesh unit. Furthermore, the exchange quantity of surface runoff and drainage pipe network flow is calculated, and the coupling of surface flood model and underground pipe network model is realized.

Description

technical field [0001] The invention relates to the technical field of hydrodynamic analysis, in particular to a method for coupling hydrodynamics of two-dimensional underground pipe networks on the surface based on spatial topology. 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 methods, it is a technical problem that needs to be solved to achieve reliable analysis of floods. [0003] Although methods such as flood analysis methods based on one-dimensional non-constant numerical models are disclose...
