Abstract: Based on the in-situ monitoring data of the post- construction settlement of the high embankment of Jiuzhai-Huanglong airport, some regressive parameters models are discussed to predict the post-construction settlement. All exponential models, power function models, root-squaring models, hyperbolic models, but logarithm models can’t disclose the laws of the post- construction settlement of the high embankment. The predicted results with logarithm models show that due to the varation of the thickness of the underlying weak stratom and the upper filled soil, the differential settlement of the high embankment is remarkable.
