Description

technical field

[0001] The invention relates to a multifunctional temperature-controlled double-chamber pressure chamber, in particular to a multi-functional double-chamber pressure chamber structure capable of realizing high precision and temperature control. Background technique

[0002] In geotechnical tests, the pressure chamber is an indispensable part of simulating the actual engineering environment. By applying external loads such as ambient pressure, vertical stress, osmotic pressure and matrix suction to the sample in the pressure chamber, it can effectively simulate the natural state of the rock. The stress distribution of the soil material can be used to conduct in-depth research on the shape and behavior characteristics of the sample, such as mechanics, penetration, and piping.

[0003] Usually, the test time required for most geotechnical tests ranges from 2-3 days to as long as 12 months. Under the long-term test load, the structure of the pressure chamber will...
