The displacement-time relationship curves are got from laboratory tests for the deformation character analysis of the soft clay in unloading condition. The stress control triaxial compression apparatus is used and remade from the strain control compression apparatus. The following conclusions are gained from the analysis of the test results: 1) when the amount of the loading and the unloading are the same, the amount of the deformation produced in the unloading process is much smaller than the amount of the deformation produced in the loading process; 2) the resilience is very small, when the portion of the unloading is small; 3) the resilience will increase sharply, when the amount of the unloading is big enough; and 4) the resilience deformation will trends to be stable, when the portion of the unloading exceeds another point. The finite element analysis software ABAQUS is used to simulate the laboratory test.
