An optimization method for the design of source control facilities in sponge cities

Abstract

The invention discloses an optimization method for sponge city source control facility design. The method comprises the following steps of setting a background reference value of a target region, wherein the background reference value includes a water yield background value and a water quality background value; determining a facility type according to the land occupation type and land conditions of the target region, performing first-level generalized simulation, performing overall rough estimation determination, meeting the requirement of total quantity control, and therefore determining the facility scale; designing specific facility parameters by adopting the facility scale obtained through generalized simulation as the basis, and performing refined simulation to determine the facility designed parameter to meet the requirement of control to be used as the basis of an establishment construction design drawing. The method has the advantages that specific stage division is performed on the target region source control facility design, multi-stage targets are cleared, layering simulation can be performed by sufficiently applying a model for different simulation modes of the source control facility, stepping control is promoted, and the planning and design efficiency can be improved from overall generalization to local elaboration.

Description

technical field [0001] The invention relates to the technical field of planning and design of sponge city construction, and specifically designs an optimization method for planning and design of source control facilities for sponge city construction. Background technique [0002] Arrangement of source control facilities in a small area is one of the important ways to construct a sponge city. In the planning and design stage, it is necessary to determine the type, scale, spatial layout and specific parameters of the facilities, and then compile the final engineering design and construction drawings. At this stage, since the facilities are not in operation and there is a lack of actual monitoring data, professional simulation software is needed to simulate and complete the planning and design of the source facilities. Therefore, making full use of the simulation function of the source facilities in the simulation software to complete the planning and design of the facilities i...

Problems solved by technology

[0005] (1) Although the current planning and design methods for source control facilities in sponge cities emphasize the use of professional models for simulation, they do not have a comprehensive understanding of the simulation methods of source facilities in the model, and the use of models is not in place, so they cannot make full use of model-related Planning and design of functional auxiliary source facilities;

[0006] (2) The current planning and design of source facilities often involves multiple departments, but because the stages are not carefully divided and specific goals are set for each stage, the goals of each department are not clear, which is not conducive to the implementation of responsibilities;

[0007] (3) The current design methods usually only use one simulation method in the model, which has limitations: only generalized simulation is performed, and the results obtained are often not accurate enough, and the specific parameters of the facility cannot be determined according to the simulation results; instead, refinement is directly carried out Simulation, it will be difficult to determine the scale of the facility, and there is also a certain degree of uncertainty in the overall layout. It is likely that repeated adjustments to the overall layout and scale will be required, resulting in meaningless duplication of labor and reduced simulation efficiency.
