Embodiment

[0050] Embodiment: This embodiment specifically relates to a method for evaluating the migration trend of polluted sites based on the interaction between surface water and groundwater and the influence of bank slope structure. This evaluation method can be applied to various types of contaminated sites such as agricultural land, construction land or reclaimed land. Environmental surveys, using the interaction between surface water body and groundwater and the impact characteristics of bank slope structure on pollutant migration, evaluate the spatial distribution characteristics of pollutants, and then guide the design of investigation programs, and evaluate the migration trend of pollutants. The specific steps of the assessment method are described below in conjunction with a contaminated site:

[0051] (1) Determine the hydrogeological conditions of the target site. The hydrogeological conditions include stratum distribution, soil and physical and mechanical parameters, permeabi...

Abstract

The invention discloses a contaminated site investigation migration trend evaluation method. The evaluation method considers the interaction between a surface water body and underground water, considers the bank slope structure of the surface water body and evaluates the migration trend of pollutants through analog computation so as to provide guidance for an investigation stationing scheme of a contaminated site. The evaluation method has the advantages that the establishment of the evaluation method can accurately evaluate the pollutant migration trend of the polluted site with the surface water body inside or nearby, can provide accurate and reliable pollutant spatial distribution information for the investigation of the polluted site, and is convenient for point distribution and implementation.

Description

technical field [0001] The invention belongs to the technical field of environmental geotechnical engineering, and in particular relates to a migration trend assessment method for polluted site investigation. Background technique [0002] After decades of industrial development in China, the soil and groundwater in the area where industrial enterprises are located have caused varying degrees of pollution. For areas with many surface water bodies, due to the dense river network, many industrial plants are built near the rivers, so that the pollutants produced by these industrial plants pollute the surface water bodies through the interaction between ground water and surface water. [0003] The interaction between groundwater and surface water occurs in the hypoflow zone between groundwater and surface water, while the bank slope of the surface water body is located in the hypoflow zone. Due to the difference in bank slope structure, the interaction between groundwater and sur...
