Abstract

One key technical problem of the Hong Kong-Zhuhai-Macao Bridge is the structural response to high winds. This study included wind tunnel tests of a conventional sectional model, a large sectional model, a full-bridge aeroelastic model and a self-supporting aeroelastic tower model for three channel bridges and non-navigable bridges. The results indicate that the original design of the Hong Kong-Zhuhai-Macao Bridge may suffer from wind effects such as flutter, unacceptable vortex-induced vibrations and tower galloping. Aerodynamic and structural modifications are given to eliminate the wind problems of the Hong Kong-Zhuhai-Macao Bridge. This research provides guidance for guaranteeing the safety of the Kong-Zhuhai-Macao Bridge in high winds.
