Multifunctional geotechnical triaxial testing system

Microcomputer controlled multifunctional geotechnical triaxial testing system
1. Overview
Microcomputer controlled multifunctional geotechnical triaxial testing system is a new type of triaxial multifunctional testing system developed by Lichuang Company. Three cylindrical unsaturated soil samples were subjected to axial pressure (
or principal stress difference (
-3) under different constant surrounding pressures (i.e. small principal stress 3
)
)), shear until failure, measure the shear strength of the soil, and then obtain the shear strength parameters, the total shear strength parameters and effective shear strength parameters of fine-grained soil and sandy soil according to the Mohr-Coulomb theory intensity parameters. This testing machine adopts computer multi-channel closed-loop digital control. Its measurement accuracy and control degree are in the leading position in the same industry. It is an ideal geotechnical testing equipment for water conservancy and hydropower, universities, colleges and scientific research institutes.
This testing machine can perform the following geotechnical tests:
Unconsolidated and undrained shear test
The sample is not allowed to drain during the entire process of applying ambient pressure and increasing axial force until failure. , used to determine the total shear strength parameters.
Consolidated undrained triaxial shear test or
After the sample is drained and consolidated under a certain surrounding pressure, and then maintained in an undrained state, the axial force is increased until failure, and the total resistance is measured. shear strength parameter, or effective shear strength parameter, and pore pressure coefficient.
Consolidation and drainage triaxial shear test
After the sample is drained and consolidated under a certain surrounding pressure, the axial force is increased until failure while allowing the sample to be fully drained. The measured Effective shear strength parameters,.
Conventional unsaturated soil triaxial test controls the measurement of pore water pressure and pore air pressure
