Abstrait:

This paper focuses on design, construction and health monitoring for a floating pedestrian bridge cross two cliffs. The substructure of the bridge is located near cliffs. The superstructure of the bridge is a curved box girder supported by a tilting cable-arch system. A parabolic steel arch spans about 100 m between two cliffs and rises 25 m above cliff levels.

The key design issues on the substructure and superstructure are included as follows: 1) 3D laser scanning techniques for modeling of rock mass structures and numerical analysis evaluations for the substructure; 2) performance investigations for the superstructure, such as form-finding for the cable-arch-girder structure, overall stability for the curved girder and human-induced vibration control with different crowd density. Rotation construction process is introduced to complete the bridge at the severe mountain site. Joint details at the bases are designed and numerical analysis for the whole construction is performed to verify the feasibility of the construction. Health monitoring considerations for cable forces and girder vibrations under working states are suggested at last.
