Abstract: Taking settlement data of 69m high embankment of an expressway as research sample, using GM (1,1) grey model which has been amended by heterogeneous fill and non-equal step settlement prediction time, and compared with the prediction results of growth curve model, it is demonstrated that these two models can predict the final settlement of high embankment better; and the grey prediction model is better predictable the non-homogeneous deformation of high embankment than the growth curve prediction model. Simultaneously, it is recognized that the prediction results of this grey model are better tallied with the settlement deformation tendency of high embankment, and can do the next work of researching, popularizing and utilization.

Key words: road engineering, high embankment, settlement, prediction model
