The Key Techniques of Zhangjiajie's Grand Canyon Glass-bottom Suspension Bridge Design

Abstract

Zhangjiajie's Grand Canyon Glass Bridge is a signature pedestrian and scenic bridge. The bridge is the spatial cable plane earth-anchored suspension with the main cable span of 430-meter-long and a stiffening box-girder span of 373-meter-long. The bridge deck is wholly constructed with transparent tempered glass panels . The lateral distance between two pylons at of the west side and the east side of the bridge is 45m and 50m respectively. This paper is intended to introduce some key techniques of the design along with the general introduction of the bridge.
