Abstract:
The main span structure of Moxiang Bridge is designed as reinforced concrete box arch with a clear span of 100 m and vector height of 16.67 m. Construction control is successfully realized in pile foundation and platform, temporary pier and capping beam, bailey beam, cuplock full scaffold and formwork, ensuring smooth construction. It is concluded that such combined supporting scheme has favorable bearing capacity, high safety factor and short construction schedule.
