Stage construction is a typical procedure for expressway embankments on soft ground. Based on the traditional hyperbolic method
a new model for prediction of settlement of stage constructed embankment on soft ground is presented. In the proposed model
soil deforms nonlinearly
and its consolidation properties vary with the magnitude of the load. The parameter a related to consolidation properties of soft soil is determined by the settlements measured at the forestage with longer preloading duration; the other parameter
the final settlement Sf
is determined by the settlements measured in shorter preloading duration at which stage settlements are to be predicted. A case study shows predicted settlements are fairly consistent with measured settlements. The proposed model is accurate and easy to operate
and can predict settlements in practical engineering in time.
