Measurement device and method for thermal characteristics of frozen soil based on thermal pulse method

Abstract

A measurement device and method for thermal characteristics of frozen soil based on a thermal pulse method, comprising heating the cylindrical heating probe with the heater at a constant power; the first temperature probe detects the temperature of the cylindrical heating probe and uploads it to the cloud via the transmission unit, while data recorder displays the temperature data of the first temperature probe and the second temperature probe in real-time; the temperature of the cylindrical heating probe is maintained at a constant level; by heating the frozen soil sample with the cylindrical heating probe, the temperature breakthrough curve of the frozen soil sample is obtained, then the volumetric diffusivity and volumetric thermal conductivity of the frozen soil sample is obtained. This invention can effectively keep the maximum spatial temperature below the freezing point, thereby enabling the estimation of the overall thermal characteristics of quartz sand and ice content.
