摘　　要：阐述了黄土的分布与性质,对黄土路堤沉降的机理及原因进行了分析。分析比较了基于实测资料预测黄土路堤工后沉降值的实用模型,包括指数模型,幂函数模型,双曲线模型。以指数模型为例,根据已建成某大坝实测数据,确定了预测模型的参数。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.
