Tongtian Spatial Prestressed Cable Bridge at Jiulong Mountain, Zhejiang

介绍桥梁结构的一种新型式—空间预应力索桥。它应用现代索结构技术 ,从结构形式和使用材料两方面对索桥进行创新 ,有效地解决了困扰这类桥发展的一些主要问题。介绍这种桥梁的设计背景、结构构造和结构特点。这种桥梁适合于跨越海峡、深谷、激流以及风景旅游区的轻荷载桥梁应用。设计所采用的钢板式索夹以及销接式结点等 。

A new bridge structure, the spatial prestressed cable bridge is described. The bridge is innovated in aspect of both structural types and materials by using the existing modern cable structure technologies and major problems that may hinder the further development of the bridge have been effectively resolved. In this paper, design background, structural details and features of the bridge are presented. The bridge proves to be applicable for light load use when they are widely used to span across straits, deep valley and at the scenic spots, and for the first time in China, steel plate style clamps and pin connection techniques are used on the bridge.
