Abstract: Owing to their great height and large volume, high-fill embankments are subject to differential settlement that often reduces their safety and stability, and therefore the post-construction settlement of such embankments should be examined carefully. This paper develops a practical creep calculation method based on the finite element method for calculation of post-construction settlement by a time-dependent UH model and the simplified one-dimensional creep deformation computation method that could be combined with the layer-wise summation method. Field observation data collected at the Chengde airport are used to verify this method. Comparison of the calculations and field data shows that new method is able to achieve reliable predictions of post-construction settlement and hence to provide useful guidance for the following construction of the airport.
