From 2019 to 2020, low-temperature creep experiments were conducted on frozen soil in Mohe and Dongying to study the creep behavior of frozen soil under temperature conditions (-25 º C, 25 º C). The data obtained from different confining pressures and temperatures of frozen soil creep experiments conducted in Qingdao, Shandong Province in 2019 and 2020, includes observation factors such as temperature, time, differential stress, creep strain, etc. The data resource collection time range is from October 20, 2019 to January 20, 2020, using a low-temperature triaxial experimental system to measure the creep strain of frozen soil under different confining pressures and temperatures. Used to establish a model of the influence of temperature and confining pressure on the creep of frozen soil.
Experimentally generated, autonomously generated.
The instruments used for data collection include the servo controlled low-temperature conventional three-axis experimental system of China University of Petroleum. Technical parameters: 1. Maximum axial force: 1000kN; 2. Test force accuracy: ± 1%; 3. Test force resolution: 1/120000; 4. Maximum piston displacement: 100mm; 5. Displacement accuracy: ± 1%; 6. Displacement resolution: 1/100000; 7. Axial deformation measurement range: 0-8mm; 8. Radial deformation measurement range: 0-4mm; 9. Deformation measurement accuracy: ± 1%; 10. Deformation resolution: 1/100000; 11. Maximum confining pressure: 100MPa; 12. confining pressure accuracy: ± 2%; 13. Resolution of confining pressure: 1/60000.
The data quality is good.
