Abstract
Compared with that of the offshore and inland long-span bridges, the wind field of marine bridges will be more complicated, and their wind resistance safety will inevitably become tougher. This paper first analyzes the status quo of wind-resistance research of long-span bridges, and then focuses on the difficulties and technical problems regarding four aspects: wind field characteristics, wind-resistant design theories, countermeasures for wind-induced vibration, and windbreak technologies for driving safety. Based on these analyses, countermeasures for guaranteeing wind resistance safety of marine bridges are proposed.
