Research on Predicting Light Soil Embankment Deformation Induced by Deep Soft Foundation Based on GM(1,N)
In order to effectively predict the settlement trend of a highway embankment on a deep soft foundation,based on some monitoring data,the grey system prediction model GM(1,N)was used to predict and analyze the settlement,and the results were compared with those of finite element method and layered settlement calculation method.The results show that the results of finite element analysis are quite different from the field monitoring data in general trend,and theoretical calculation can only provide the prediction of final settlement,which cannot meet the requirements of construction stage deformation prediction.However,GM(1,N)model has a good prediction effect on embankment set-tlement in a short period of time,and the prediction data will be larger when the time is longer.
