Frozen soil is a soil medium which is extremely sensitive to temperature and contains abundant groundwater. Frozen soil has rheological properties due to moisture migration and phase change characteristics. Its long-term strength is far lower than the transient strength characteristics, and has thawing sinking property and frost heaving property. These features create two major engineering problems faced when constructing traffic engineering structures in frozen soil areas: thawing, sinking and frost heaving. Among them, roadbeds, bridges, tunnels and the like all suffer from these two major engineering problems. Therefore, the method for monitoring the road freezing depth and judging the freezing state is a problem to be solved urgently in traffic engineering.
The existing method for measuring the freezing depth of soil is to fill distilled water, and vertically place a plastic pipe with two sealed ends in a pipe barrel buried in the soil. It is clear which section is frozen and which section is not frozen. The method is actually used for observing the position of the ground temperature of 0 ℃ and cannot accurately measure the position of frozen soil.
Therefore, a soil freezing depth measurement system is a highly-needed problem.
