Device for simulating freezing and thawing cycle process of frozen soil

Abstract

The invention discloses a device for simulating the freezing and thawing cycle process of frozen soil. The device comprises a transparent container, an upper cold bath disc, a lower cold bath disc, a water and soil partition plate, a cavity partition plate and a cold bath tank, the upper cold bath disc covers the top of the transparent container; the lower cold bath disc covers the bottom of the transparent container; the water and soil partition plate is arranged in the transparent container and detachably arranged on the lower cold bath disc, and a water storage cavity is formed between the water and soil partition plate and the lower cold bath disc; the cavity partition plate is arranged in the transparent container, is detachably connected with the transparent container, and is used for vertically separating the interior of the transparent container into a plurality of experiment cavities; the cold bath tank is connected and communicated with the upper cold bath disc and the lower cold bath disc, and the cold bath tank is used for regulating and controlling the temperature change of the upper cold bath disc and the lower cold bath disc in the experiment process; and therefore, during application, different soil bodies can be put into different experiment cavities, so that synchronous experiment comparison is carried out, and the problem that multiple simulation experiments cannot be carried out simultaneously in the prior art is practically solved.

Description

technical field [0001] The invention relates to the technical field of studying the freeze-thaw cycle process of frozen soil, in particular to a device for simulating the freeze-thaw cycle process of frozen soil. Background technique [0002] The freeze-thaw effect caused by the natural environment is a long-term process for the soil. In order to meet the needs of engineering construction and obtain the performance changes of the soil under the freeze-thaw cycle as soon as possible, the indoor accelerated test is an important means to study the freeze-thaw characteristics of the soil. The experiments on frozen soil are mainly divided into two aspects, one is to study the changes of physical and mechanical properties of frozen soil before and after experiencing freeze-thaw cycles, and the other is to study the changes of frozen soil during the freeze-thaw cycle process. Stress-strain, temperature, moisture and salt migration laws. [0003] Depending on the purpose of the tes...
