Abstract: Based on the observed settlement data, the ultimate settlement prediction work was performed at the west end of the sloped area in Chengde Airport construction by using exponential function, hyperbolic function and Pearl Model methods. The prediction accuracy of each method are carefully analyzed and the hyperbolic function method was used to predict the ultimate settlement. It is concluded that the ultimate settlement at survey points at the west end should be 58.24 mm. The ultimate settlement prediction work can provide a viable method for the post construction performance of the airport structures.

Key words: Settlement Predictions, Exponential Function Model, Hyperbolic Function Model, Pearl Model
