Abstract

A frost heave measuring instrument for realizing hydrothermal-mechanical coupling, comprising a sample loading system, a refrigeration system and a data acquisition system. The sample loading system includes an assembly frame, the assembly frame has a sample placement chamber, and a water replenishing structure for replenishing the sample is arranged on the assembly frame. The invention has exquisite structure and reasonable design. The heat-conducting plate is connected to the refrigerator, and the heat-conducting plate provides cooling capacity to realize temperature control of the sample. The invention can control the moisture content and temperature of the sample, and install multiple sensors on the assembling frame to measure the parameters such as temperature, moisture, frost heave force, frost heave displacement and the like of the sample. The invention can realize the coupling effect of water, heat, force and other factors, the test results are accurate, scientific and rigorous, and a water replenishing structure is provided, which can replenish water to the sample through the water replenishing structure, thereby changing the moisture content of the different soil layers of the sample in time.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and more specifically relates to a frost heave measuring instrument for realizing the coupling effect of water and heat. Background technique [0002] Permafrost refers to various rocks and soils below zero degrees Celsius and containing ice. Generally, it can be divided into short-term frozen soil (several hours / days to half a month), seasonal frozen soil (half a month to several months) and permafrost (also known as permafrost, which refers to the frozen soil that lasts for two years or more. unmelted soil). Frozen soil has rheological properties, and its long-term strength is much lower than the instantaneous strength characteristics. Because of these characteristics, engineering structures in permafrost regions must face two major dangers: frost heave and thawing settlement. [0003] In my country, the distribution area of ​​permafrost regions is 2.068×106km 2 , the distri...
