Abstract

The invention provides an unsaturated soil thermal physical parameter testing system. The unsaturated soil thermal physical parameter testing system is composed of a soil sample control system, a thermal physical parameter testing system and a data acquisition system, wherein the soil sample control system is composed of a pressure plate instrument unit, a pressure control unit and a water quality measurement unit; and the pressure plate instrument unit comprises a test part chamber, an annular cutter, a ceramic plate, a fixed bolt, a base and a water pipe. The pressure control unit is used for controlling air pressure in the test part chamber; the pressure control unit comprises a pressure gauge, an air compressor, an air valve, an air pipe and a sealing bolt; the water quality measurement unit comprises a water groove, a graded tube, a balance and a beaker; the thermal physical parameter testing system is composed of a moisture content tester and a thermal physical property tester; and the data acquisition system is composed of a data acquisition unit and a computer. With the adoption of the unsaturated soil thermal physical parameter testing system, the disadvantage in the prior art that thermal physical parameters of unsaturated soil cannot be accurately measured can be overcome, and the relation between the moisture content in a soil body and the thermal physical parameters can be researched.

Description

technical field [0001] The invention relates to a test system and method for thermal physical property parameters of unsaturated soil, in particular to a test system and method for thermal physical property parameters corresponding to unsaturated soil under different water content conditions. Background technique [0002] As we all know, the energy problem restricts the economic development of human society, and the fundamental way to solve the energy problem lies in renewable energy. Geothermal resource is a typical clean energy, which has the advantages of sustainable, renewable and comprehensive utilization, and has huge economic value. Ground source heat pump technology is a common means of utilizing shallow geothermal resources, and refers to a new energy utilization technology that utilizes shallow geothermal energy for heating and cooling. Generally, the ground source heat pump technology utilizes the huge heat storage and cold storage capacity of the underground roc...
