Abstract

The theoretica~ semi-empirica~ and empirical methods to design the ultimate pile capacity are widely used. However, the uncertainties of the soil parameters sometimes could lead to overestimation of ultimate pile capacity which makes the increasing of the cost of the project. This paper presents the analysis of the actual and designed ultimate pile capacity, and the application of Bayesian approach fur inverse analysis as a method to obtain the unit shaft resistance and the unit base resistance based on the pile load test results at Ara Damansara. The result fur this project is limited to the area around Ara Damansara only. In this paper, comparison of unit shaft resistance and unit base resistance between bored pile and driven pile were done. Prior knowledge for unit shaft resistance and unit base resistance are based on Standard Penetration Test (SPT) N value. From the prior knowledge, Bayesian approach can be applied to obtain the new ultimate pile capacity based on the pile load test results. The Bayesian approach can be updated when new information is obtained, therefore further to reduce the uncertainty of the unit shaft resistance and unit base resistance. Thus, the ultimate pile capacity can be design more accurate by applying Bayesian approach as part of the design tool.
