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.
