| Abstract: | It is an important geotechnical problem to predict the settlement of the soft soil foundation.With Grey Theory and the cubic interpolation spline function,we established an equal time-span GM(1,1) model to predict the settlement of soft clay foundation,and MATLAB language is applied to compile the program.The simulation of the project construction indicates that the model is feasible with a comparatively precise prediction.The method can be a useful reference to the construction. |
