Abstract

The invention relates to the field of hydrogeology and specifically relates to an aeration zone solute transport simulating device and method. The aeration zone solute transport simulating device comprises a solution box, a control valve, a centrifugal box and a rainfall disk, wherein the solution box is connected with the centrifugal box through a flow guiding pipe, the control valve is arrangedon the flow guiding pipe, the flow guiding pipe is connected with the rainfall disk, the rainfall disk is arranged at the upper end of the centrifugal box, a solution in the solution box can enter thecentrifugal box through the flow guiding pipe and the rainfall disk. The aeration zone solute transport simulating device can simulate a solute transport process in an unsaturated zone, can more accurately simulate gravitational fields, materials and hydrogeological conditions and can simulate several important control parameters of thermal convection, capillary phenomenon and the like for controlling pollutant transport. The method disclosed by the invention has the advantages of good experimental repeatability, good experiment simulation effect, obvious time-lapse and scale effects and thelike.

Description

technical field

[0001] The invention relates to the field of hydrogeology, in particular to a device and method for simulating solute migration in a vadose zone. Background technique

[0002] In recent years, in addition to the research on traditional engineering fields such as dams, slopes and retaining walls, foundations and tunnels, and foundation treatment, centrifugal model tests have benefited from the development of measuring instruments and the improvement of model preparation technology. Great progress has been made in new research fields such as environmental geotechnical engineering and earthquake engineering. The centrifugal model is also widely used in water solute transport. The transport of water, chemicals and heat in the unsaturated zone is a rather complex coupled flow problem with cross-effects of various gradient effects. So far, a lot of research work has been done on the migration and transformation of solutes in soil and unsaturated zones, and a lot ...
