Based on the mass of contrast tests

creep consolidation characteristics and calculating models of typical soft soil from Guangdong are systematically studied. The test results show that the deformation proportion of consolidation and secondary consolidation is related to the factors including initial load and loading ration in test

consolidation degree

water content and void ratio of soil samples. The complications of affecting secondary consolidation coefficient are loading history

loading ration and current consolidation state of soft soil. Preloading can reduce secondary consolidation coefficient. The scale between second consolidation coefficient and compression index is constant

about 0.025-0.10. Direct shear-creep characteristic is related to vertical consolidation pressure; and the creep rule presents strain hardening characteristics. Consolidation action can play down the creep effect

so the creep characteristic in triaxial test is connected with drainage condition. In coordination loading addition

the relationship between deviator stress and axial strain is nearly straight-line in CD test; but in CU test

it assumes nonlinear and there is visible yield characteristics. When the continuous loading manner is adopted in UU test

the failure strength will be improved. Bases of above results

the models of creep and consolidation are analyzed considering respectively nonlinear constitutive relationship and shear drainage condition.
