Percolation and solute migration measurement method based on high-density resistivity method

Abstract

The invention provides a seepage and solute migration measuring method based on a high-density resistivity method. The method comprises the following steps that a test master control computer is placed at a position suitable for a tester and is in wireless connection with a centrifugal machine load host, a high-density resistivity measuring device is connected with the centrifugal machine load host through a data line, and electrodes are electrically connected with the high-density resistivity measuring device through wires. A body model box is fixed to one end of a centrifugal rotary arm, and the electrodes are evenly distributed on the edge of the body model box clockwise. A liquid storage box is fixed to the upper portion of a to-be-measured test earth material in the body model box. The test master control computer sends a test start / stop command to the high-density resistivity measuring device, and the high-density resistivity measuring device carries out a test action or stops the test action according to the command. The seepage and solute migration measuring method based on the high-density resistivity method can meet three-dimensional damage-free real-time measurement needs.

Description

technical field [0001] The invention relates to a method for measuring seepage and solute migration based on a high-density resistivity method, in particular to a method for measuring seepage and solute migration based on a high-density resistivity method that is applied in a geotechnical centrifugal model test. Background technique [0002] Geotechnical centrifugal model test is a very important technical method in the field of geotechnical engineering, and it is also one of the powerful tools for the study of seepage and pollutant migration. In geotechnical engineering, the self-weight stress of soil usually dominates, and the mechanical and hydraulic properties of soil vary with the stress level. The small-scale centrifugal model test uses the same material as the prototype, and achieves the same stress level as the prototype in the high acceleration field formed by the geotechnical centrifuge, so that the stress and strain of the model and the prototype are equal, the de...

AI Technical Summary

Problems solved by technology

The sampling analysis method can obtain more accurate medium characteristic data, but usually cannot be measured and analyzed in real time, and the information obtained during the test process is limited, and the overall measurement accuracy will be affected by factors such as the location of the sampling point and the number of samples

[0004] Therefore, the existing measurement methods more or less have some typical defects and deficiencies. Geotechnical engineering testing urgently needs to develop a non-destructive, three-dimensional, real-time measurement method that can adapt to the supergravity centrifugal environment and ensure high precision. method
