Embodiment Construction

[0065] In order to make the purpose, content and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0066] The purpose of the present invention is to intuitively and in multiple time scales to reflect the effect of the groundwater pressure extraction scheme on the groundwater. Combined with the hydrogeological conditions of the research area, the invention generalizes boundary conditions and aquifers, determines each source-sink item and hydrogeological parameters, establishes a GMS-based groundwater flow model, and identifies and verifies the model. Input the pressure extraction amount corresponding to the groundwater pressure extraction scheme as the source-sink item into the model, set different simulation times, run the model, and analyze the results to know the effect of the groundwater pressure extraction scheme. The inventi...

Abstract

The invention relates to a method for analyzing the effect of an underground water pressure mining scheme based on a GMS, and belongs to the technical field of numerical simulation. According to the method, the hydrogeological conditions, the generalized boundary conditions and the aquifer of a research area are combined, all source and sink items and hydrogeological parameters are determined, the GMS-based groundwater flow model is established, and the model is identified and verified. The pressure mining quantity corresponding to the underground water pressure mining scheme serves as a source sink item to be input into the model, different simulation time and operation models are set, the result is analyzed, and the effect of the underground water pressure mining scheme can be obtained. According to the method, the direct underground water flow field graph under the influence of the underground water pressure mining scheme under different time scales and the underground water resource quantity change value of the research area can be obtained, so that the direct understanding of the effect of the underground water pressure mining scheme is realized.

Description

technical field [0001] The invention belongs to the technical field of numerical simulation, and in particular relates to a method for analyzing the effect of a groundwater pressure extraction scheme based on GMS. Background technique [0002] Most of the existing technologies use the water balance method, the comprehensive index method, and the gray correlation analysis method to analyze the effect of the groundwater pressure extraction scheme. [0003] Among them, the water balance method analyzes the recharge and discharge terms of the groundwater system to obtain the profit and loss of the water volume of the groundwater system, which is one-sided and inaccurate. [0004] The comprehensive index method constructs the evaluation index set of the groundwater pressure extraction effect, and the evaluation of the groundwater pressure extraction effect is processized. [0005] The grey relational analysis method is based on the similarity or dissimilarity of the development ...
