Abstract: The creep behavior of saturated sands is studied by uniaxial compression tests. The samples were taken from the aquifers of Changzhou in Jiangsu Province. Based on the test results, the relationship of stress-strain-time for saturated sands is obtained; and it could be expressed as power functions. The test results show that the strains for sands depend not only on the stresses exerted on them but also the time elapsed. That is to say that the sands have characteristics of nonlinear creep. The conclusion is very helpful to study the land subsidence due to extracting groundwater.

Key words: saturated sand, nonlinearity, creep model
