Large-scale low-temperature geotechnical simulation test system

Abstract

The invention discloses a large-scale low-temperature geotechnical simulation test system, which comprises a heat insulation cover, a bottom moisture dynamic supply system, a temperature detection and control system and a signal detection and data acquisition processing system, wherein the heat insulation cover provides low-temperature simulation test environment for a tested body; the bottom moisture dynamic supply system automatically replenishes the tested body with water from the bottom of the tested body to the top thereof; the temperature detection and control system controls and adjusts the temperature inside the heat insulation cover; and the signal detection and data acquisition processing system detects, analyzes and processes related parameters of the tested body. The test system has the advantages of simple structure, reasonable design, low energy consumption, strong controllability and high cost performance, and can effectively solve overcome poor operability, high cost, non-ideal test effect and other defects and deficiencies of the prior large-scale low-temperature test system.

Description

technical field [0001] The invention belongs to the technical field of geotechnical testing, and in particular relates to a large-scale low-temperature geotechnical simulation test system. Background technique [0002] With the rapid development of the highway industry, some special soil (such as permafrost, saline soil, etc.) foundation engineering disease has increasingly become the bottleneck of the development of this industry. At present, most of the experimental research on the above-mentioned diseases involved is carried out in low-temperature laboratories. However, due to the relatively large area of ​​the laboratory, it consumes a lot of energy for cooling and heating. In addition, the cycle of low-temperature simulation experiments is long, resulting in many large-scale low-temperature experiments. Energy consumption funds were stranded. In addition, due to the influence of ambient temperature, it is difficult to control factors such as temperature and moisture in...
