Abstract

The prediction of post-construction consolidation and settlement is critical for assessing the deformation of a soft soil subgrade. One-dimensional consolidation creep test was conducted to analyze the creep characteristics of a soft silt subgrade of a highway constructed near Qinghai Lake. The test results showed the following. The stress-strain curve of the silt was nonlinear. The higher the stress, the sooner the soil entered the secondary consolidation stage. The transition between the primary and secondary consolidation stages occurred at 100 min. The generalized Kelvin model, Burgers model, Singh-Mitchell model, and power function empirical model were selected to fit the experimental results and obtain the model parameters. The Singh-Mitchell and the power function empirical model provided the best performances for reflecting the creep characteristics of the Qinghai Lake silt. Thus, these models can be used to estimate the post-construction settlement and deformation of this soil type.
