Pore Pressure and Strength Behaviors of Reconstituted Marine Sediments Involving Thermal Effects
The thermal effects on the pore-water pressure and strength behavior of marine sediments from the South China Sea were studied by using temperature-controlled triaxial shear tests on reconstituted specimens. The experimental program included consolidation at a temperature of 5°C, undrained and drained heating from 5°C to 50°C, and undrained triaxial shear at 5°C and 50°C. The results indicated that the normalized heating-induced pore-water pressure increased with increasing temperature at the undrained heating stage. The undrained shear strength of the specimens under undrained or drained heating was 14.1% lower or 11.2% higher than that of specimens at 5°C, respectively. The shear-induced pore-water pressure of the specimens under undrained and drained heating was lower than that of the specimens at 5°C by 60.5% and 20.3%, respectively. The increasing temperature caused an increase in the slope of the critical state line (M).
