Abstract Settlement after construction is one primary problem of high-filled embankment. In this paper a method of prediction for settlement after construction was developed. A general Kelvin model was adopted to depict constitutive relationship of filling material. The bottleneck of the problem is how to obtain reliable material parameters for numerical calculations. Based on field monitoring data，back analysis approach using a 3D FEM method，an orthogonal numerical experiment，and a regression and optimization analysis was conducted to calculate the visco-elastic parameters. With these calibrated parameters，the settlement after construction of a 37 m high-filled highway embankment was predicted. The results show higher accuracy and good agreement with monitoring data. The method can be used to predict settlement after construction of high-filled embankment.
