The device mainly consists of a gas supply system, a gas concentration display recorder, a gas pressure display recorder, a sleeve, a gas concentration sensor, a gas pressure sensor, a porous gas-permeable tube and a conical penetration head. The gas diffusion coefficient and permeability coefficient of the unsaturated soil can be obtained by only measuring the gas pressure value, the gas concentration value and the corresponding gas flow value of an unsaturated soil layer at a depth required to be tested, and substituting same into calculation formulae of the gas diffusion coefficient and permeability coefficient. The testing process of the method is simple and fast, and is low in cost, simple in operation and convenient in calculation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device and method for in situ penetration measurement of gas transport parameters in unsaturated soil layer","description":"A device and a method for in situ penetration measurement of gas transport parameters in an unsaturated soil layer.
