EXPERIMENTAL RESEARCH ON CREEP CHARACTERISTICS OF ZHANGZHOU SOFT SOIL

Soft soil has a notable time effect, understanding thoroughly the behavior and mechanism of creep have significance in describing correctly the engineering behavior of soft soil. Influences to creep which are caused by the factors such as relationship of the strain to time, the deviation stress and strain, the pore-water pressure and time and drainage condition have been analyzed according to the experiment which carries on triaxial creep tests of Zhangzhou soft soil based on different surrounding pressure, different level of deviation stress and different drainage condition. Then parameters were fitted according to the Singh-Mitchell empirical model using the test data, creep equation of Zhangzhou soft soil was given in consolidated-undrained triaxial tests.
