The invention discloses a soil electrical parameter time-space distribution indoor test system under a freezing and thawing cycle and a working method. The system comprises a soil molding device and asoil test device. The soil test device comprises conductive sheets, wherein the two conductive sheets are set at two ends of the soil molding device, and the two conductive sheets are electrically connected through utilization of a first lead wire; conductive electrodes, wherein a plurality of conductive electrodes are inserted into the soil test device from a side wall of the soil molding device, and the plurality of conductive electrodes are electrically connected through utilization of a second lead wire; and a test assembly, wherein the test assembly is electrically connected with the conductive sheets and the conductive electrodes. The system and the method have the following beneficial effects that on the basis of a soil electrical parameter test method, a system for carrying out anindoor rapid test on electrical parameter time-space distribution of soil with different moisture content and compaction degree, under a freezing and thawing cycle effect is developed, a relationshipcan be established among parameters such as resistivity, temperature and displacement change, tested by the system, and the relationship can be applied to later soil physical and mechanical propertyevaluation.

Description

technical field [0001] The invention relates to the field of engineering geology, in particular to an indoor testing system and working method for the time-space distribution of soil electrical parameters under freeze-thaw cycles. Background technique [0002] In seasonally frozen soil areas, the physical and mechanical properties of soil will change under the action of freeze-thaw cycles, and the existing methods for testing physical and mechanical parameters of soil are mainly through indoor experiments with borehole sampling, which has disadvantages such as low efficiency. The soil resistivity, which characterizes the conductivity of soil, is an important parameter for studying soil microstructure and physical and mechanical properties, metal soil corrosion, and grounding of power systems.
