Abstract

The invention discloses a haplopore dilution method for determining the seepage direction by electrical conductivity, belonging to the field of seepage and underground water movement observation. The method comprises the steps of measuring hole positions and drilling holes, selecting a tracer according to the difference of the electrical conductivities of field drilling water bodies and determining the seepage direction by using an analytic technology for adsorbing a tracer sand body. The method has simple, convenient and reliable operation; the tracer is selected from a nontoxic strong electrolyte solution or a deionized water solution; in addition, with clear and definite principle, the invention has simple, convenient and safe measuring process, correct and reliable result, environmental protection and safety and can completely replace the traditional method for determining the flow direction of radioactive haplopore.

Description

technical field

[0001] The invention discloses a conductivity single-hole dilution method for measuring the seepage direction, which relates to the measurement of groundwater movement by a tracer dilution method, in particular a method for calculating the seepage direction by measuring changes in conductivity, which belongs to the field of seepage and groundwater movement observation. Background technique

[0002] The principle of the tracer dilution method to measure flow rate was first proposed by Kocherin. The basic principle is that in a vertically exposed aquifer, the aquifer is isolated with a plug, and then a certain tracer is used to mark the groundwater, and the water body Mix evenly, the concentration of the tracer will decrease continuously with the water flow, and the tracer concentration before and after the section of the water column is measured twice with the probe, and the infiltration flow rate of the aquifer can be calculated. Later, the method was gradual...
