Abstract

The invention belongs to the field of soil detection, and particularly relates to a measuring method and measuring equipment for measuring unfrozen water content of frozen soil. The measuring method comprises the following steps: measuring the initial mass of a frozen soil sample; putting the frozen soil sample into a container through which the volume can be read, then injecting water into the container until the frozen soil sample is submerged to obtain a first soil-water mixture, and reading the volume of the first soil-water mixture; melting soil ice in the first soil-water mixture to obtain a second soil-water mixture, and reading the volume of the second soil-water mixture; in combination with the volume of the first soil-water mixture and the volume of the second soil-water mixture,calculating the volume of the soil ice in the frozen soil sample; in combination with the volume of the soil ice, deducing the mass of unfrozen water in the frozen soil sample. The measuring equipment comprises the container, wherein the container comprises a base and an upper end cover arranged at the top end of the base; the upper end cover is provided with scale lines. By the measuring method,the measuring cost is low, the operation is convenient and fast, the time and the labor are saved; the measuring equipment is simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of soil detection, and in particular relates to a method and equipment for measuring unfrozen water content in frozen soil, which is suitable for measuring the water content in natural frozen soil and artificial frozen soil in the field and indoors. Background technique [0002] Frozen soil refers to rock or soil with a temperature below 0°C and ice crystals inside. When the soil is frozen, part of the liquid water in the soil pores is transformed into solid ice. At this time, the soil is a multiphase composite system composed of soil particles, air, ice and unfrozen water. Due to the effect of the surface energy of soil particles, a certain amount of unfrozen water is always maintained in the frozen soil, and the dynamic balance between the content of unfrozen water and the temperature is maintained, which is an important index for evaluating the water migration characteristics in frozen soil. The accurate...
