| Abstract: | The distribution and the nature of loess are expounded and then the mechanism and the cause of loess embankment settlement are analyzed.The valuable models based on the measured data for forecasting post-construction settlement of loess embankment are analyzed and compared,including the exponential model,power function model and hyperbolic model. Finally,in the case of the exponential model,the parameters of the forecasting model are determined according to the measured data of some dam. |
