Description

technical field [0001] The application relates to the fields of groundwater hydrodynamic simulation and movement dynamics of groundwater pollutants, and in particular relates to a groundwater seepage simulation experiment device and a method of use. Background technique [0002] With the advancement of modern science and technology and the development of society, the traditional water ecological environment has been polluted to varying degrees, and the water resource environment has also been seriously threatened. However, the law of groundwater movement is extremely complex, and often has the characteristics of large spatial scale and long time; In laboratory experiments, it is often difficult to control the hydrological conditions, boundary conditions, recharge conditions and formation lithology in the model study area. [0003] The indoor groundwater seepage physical model experiment is an important means to study the migration of pollutants in soil and groundwater at hom...

AI Technical Summary

Problems solved by technology

At present, the groundwater model devices used in the laboratory are relatively simple, basically one-dimensional soil columns or single-function

One-dimensional soil columns have limitations: usually one-dimensional soil columns simulate the infiltration of water in the soil and the dispersion of pollutants under a certain hydraulic gradient, and cannot consider the change of hydraulic gradient, anisotropy of seepage soil and spatial anisotropy. qualitative; few controllable conditions: traditional indoor one-dimensional or two-dimensional models generally cannot flexibly control the internal hydraulic gradient, pollutant input location, observation and sampling location, etc.; the simulation situation is single: some hydrogeological characteristics of the simulation area are Important factors affecting groundwater movement, such as topography, rivers and lakes, human influence, geological faults, special geological structures, etc., cannot be taken into account by traditional models; there is no room for subsequent upgrades of functional modules: with the deepening of research, model functions and parameters need to be constantly adjusted , however, the existing models generally do not consider follow-up improvements, and the reuse rate is low, so there is an urgent need for a multi-soil structure groundwater seepage simulation experimental device
