Temburong Bridge, Brunei – Independent Design Check

摘要

The new 30 km Cadangan Projek Jambatan Temburong (Temburong Bridge Project) in Brunei will connect the relatively isolated district of Temburong with the more developed Brunei-Muara district. For a project of this significance, an independent category 3 design check has been carried out of the tender design. The check includes structural and geotechnical verification of the 13km long marine viaduct, two cable-stayed bridges across the navigation channels, and three tunnels. The paper describes the objective and process of the independent design check. The checker provides comments to the design drawings and the design basis, and the designer provide replies. The checker has to set up completely independent analysis models. As an example, the finite element models of the pile foundation and the deck of the cable-stayed bridges is presented. For the cable-stayed bridges the construction process and the cable rupture analysis is discussed.
