C123 soil creep test system YXSZ-1
Overview:
The soil creep test system is a stress-controlled triaxial soil creep test system independently developed by our company in accordance with the current relevant standards and specifications, referring to relevant domestic and foreign documents. This instrument is mainly used for triaxial creep compression test of soil to study the creep characteristics of soil. At the same time, it can also do K0 lateral pressure coefficient creep test, pore pressure creep test, and uniaxial soil creep test with related test equipment. Test etc.
Test purpose: The soil is subjected to long-term triaxial creep compression tests on various soils under different confining pressures and different stress ratios. Using the viscoelastic rheological model, the creep coefficients of various soil bodies in non-destructive conditions are obtained. At the same time, a flexible variable model is used to simulate the creep behavior during failure, and to test the strength, deformation characteristics, deformation rate, and time influence factors of the soil under different conditions, which provides a general basis for predicting the long-term mechanical stability of the soil. Through the influence of different confining pressures on the creep deformation of the soil, the aging deformation of the soil is analyzed.
