Pile Foundation Construction for North Port Berths 12 13 at Port Klang

摘要

The reconstruction of Berths 12 and 13 at Port Klang, Malaysia into multi-purpose container berths is a major upgrading exercise. The reconstruction of these wharves involves the systematic demolition of the existing wharf structure. This is then followed by installation of new piles and a new reinforced concrete deck slab. The soft sediments accumulated beneath the existing wharves render significant geotechnical risks with regards to the stability of the sediment mound and its effect on the structure and the adjacent berths. Early studies indicated that the sensitivity of the soft sediments would become predominant factors when considering pile installation works within the sediment mound. This paper describes the geotechnical risks attached to the project and the steps taken to mitigate these risks during the construction of the foundations for the new structures.
