The settlement of a soft soil ground often manifests as a complicated nonlinear feature at time sequence due to the influence of many factors. It is characterized by limited data, instability, etc. thus, use of the existing experience and knowledge is verylmportant in settlement analysis of a soft soil ground. The prediction method for the settlement of a soft soil ground with the engineering practice is proposed.
