Abstract
The performance of many geotechnical works such as deep foundations is more often governed by displacement requirements. The estimation of pile foundation displacements involves model errors and uncertainty in model parameters. In this study, a sensitivity analysis of settlements of single piles in Hong Kong to model parameters is conducted using a first order, second moment method. The parameters that contribute most to the uncertainty of settlements are found to be the total unit weight, the initial deformation modulus, and the internal friction angle of the soil. Accordingly, these parameters should be carefully characterized in site investigations.
