Description
Background technique [0001] The invention relates to the technical field of soil impedance testing, in particular to a device and a testing method for testing soil impedance under different temperature paths. Background technique [0002] Soil is a multiphase heterogeneous system composed of solid, liquid and gas, and its properties are quite complex. Impedance is used in electrical circuits with resistance, inductance, and capacitance to analyze the structure and properties of a system. The impedance of the soil can not only reflect the basic physical and mechanical properties of the soil, such as the water content, void ratio, saturation, compaction, and salt content of the soil, but also reflect the solid-liquid phase inside the soil. The structure and property characteristics between phase and gas phase, such as matrix suction, volumetric water content, solid-liquid interface capacitance, resistance, etc. [0003] At present, the research on soil impedance does not inv...
