Roof rainfall runoff simulation method and device, computer equipment and storage medium

Abstract

The invention relates to a roof rainfall runoff simulation method and device, computer equipment and a storage medium. The method comprises the following steps: receiving a to-be-simulated flow fieldarea sent by a terminal, and establishing a grid area corresponding to the to-be-simulated flow field area; obtaining simulation parameters corresponding to the to-be-simulated flow field area, and querying model boundary conditions corresponding to the to-be-simulated flow field area; generating a runoff simulation model according to the simulation parameters and the model boundary conditions; and obtaining a target runoff simulation result corresponding to the to-be-simulated flow field area through the runoff simulation model and the grid area. Inaccurate and incomplete simulation of the roof runoff caused by simulation only depending on actual experiments can be avoided. Simulation calculation can be conducted on areas, affected by wind power, of rainfall runoff of different areas of abuilding roof, qualitative analysis can be conducted on the influence degree of the areas, and therefore the integrity and accuracy of roof rainwater drainage system design can be improved.

Description

technical field [0001] The present application relates to the technical field of computer simulation, in particular to a roof rainfall runoff simulation method, device, computer equipment and storage medium. Background technique [0002] In the construction industry, the building roof rainwater drainage system needs to timely and safely drain the rainwater that falls on the roof to the outside, such as to the outdoor ground or rainwater pipes. Therefore, in the design process of the roof rainwater drainage system, it is necessary to consider different environmental factors. [0003] Traditionally, in the design process of roof rainwater drainage systems, environmental factors that may affect roof runoff are often selected based on experience, that is, different environmental parameters are selected for experiments, and the selected environmental parameters are usually convenient. Environmental parameters for the experiment, so the selected environmental parameters are not c...

[0003] Traditionally, in the design process of roof rainwater drainage systems, environmental factors that may affect roof runoff are often selected based on experience, that is, different environmental parameters are selected for experiments, and the selected environmental parameters are usually convenient. The environmental parameters of the experiment, so the selected environmental parameters are not comprehensive or can not meet the ideal test conditions, and relying entirely on actual experiments for simulation results in inaccurate simulation of roof runoff, or can not obtain test results under ideal conditions
