Problems solved by technology

[0005] Regardless of the current national norms or published literature and patents, the design of the storage tanks involved is a traditional design, which cannot effectively guarantee the superiority of the layout scheme of the storage tanks; It involves the use of genetic algorithms, particle swarm optimization algorithms and other optimization algorithms. These algorithms require thousands of iteration simulation calculations (population size 50-100, iteration number 100-500), which consume a lot of time and power consumption. Therefore, the layout The efficiency of program determination is also relatively low

Embodiment 1

[0054] This embodiment takes Beijing as the background, combining figure 1 , use the following method to determine the layout scheme of the storage tank of a drainage system A (the system has 12 sub-catchments, 14 pipe sections, 14 nodes and 1 outfall):

[0055] First, introduce the concept of elasticity and determine the calculation formula of the elasticity index. This method takes the system without a storage pool as a benchmark, and calculates the system's elasticity index according to formula (1).

[0056] Set up a single storage tank in the system (j=1, each node is carried out sequentially, that is, the number of storage tanks is 1), and under the assumption that the outlet of the drainage system is blocked and the extreme rainfall (rainfall occurs once in a century), one by one Through MATLAB+SWMM simulation calculation, the basic data required for elastic index calculation is obtained. According to the formula (1), the system elasticity of all schemes (j=1) when sett...

Abstract

The invention discloses a method for rapidly determining an optimized layout scheme of a storage tank, and belongs to the technical field of urban drainage. The method comprises the following steps: (1) calculating an elastic index data element set R0 through an improved elastic index calculation formula by taking a system without a regulation and storage tank as a reference; (2) calculating an elastic characterization index through addition, preferably selecting a layout scheme elastic characterization index set RN +, and obtaining a decrement simulation optimization scheme set RN + 30; and (3) performing simulation and elastic index calculation and sorting on the decrement simulation optimization scheme set again to obtain an optimal layout scheme or a better layout scheme of the regulation and storage tank. By adopting the method, the system elasticity and the layout scheme under the condition that the urban drainage system is provided with one or more regulation and storage ponds can be quickly evaluated, the evaluation result is quicker and more objective, the operability is high, the efficiency of determining the layout scheme of the regulation and storage ponds is greatly improved, and the optimization layout planning design of the storage tank of a new drainage system can be better guided.

Description

technical field [0001] The invention belongs to the technical field of urban drainage, and more specifically relates to a method for rapidly determining an optimal layout scheme of a storage tank. Background technique [0002] Storage ponds are an important part of urban waterlogging prevention and control systems, and are widely used in many cities for waterlogging prevention and control. The number and layout of storage tanks are crucial to urban drainage and waterlogging control effects. Therefore, it is of great significance to discuss the determination method of the optimal layout scheme of storage tanks. At present, the design of storage tanks in the field of urban drainage mainly combines the current national standards "Code for Design of Outdoor Drainage" GB 50014-2006 (2016 edition), "Technical Specifications for Urban Waterlogging Prevention" GB 51222-2017 and "Technical Specifications for Urban Rainwater Regulation and Storage Engineering" "GB 51174-2017. Howeve...
