Abstract: Based on a series of laboratory tests with undisturbed samples obtained from Nansha of Guangzhou,including triaxial compression test,triaxial creep test and one dimensional compression test,creep deformation characteristics of soft soils were researched.It was shown that there were many factors impacting on the creep characteristics of soils,such as the initial degree of consolidation,drainage condition,load ratios and so on;and the relationship between coefficient of secondary consolidation and consolidation pressure depended on preconsoildation pressure and load ratios in the test.
