CREEP BEHAVIOR OF SEDIMENTARY SOFT ROCK UNDER TRIAXIAL COMPRESSION
沉积软岩的三轴蠕变实验研究及分析评价

In the laboratory of constant temperature-humidity, triaxial compression creep experiments were conducted under different stress states on three kinds of sedimentary soft rock. A lot of experiment results are examined and analyzed by five-element rheologic model and constitutive equation of variable compliance type. The relationship among many factors are obtained on the creep behaviour of sedimentary soft rock, such as axial strain, axial strain ratio, axial stress, and axial stress ratio.
