摘　　要：由于桥址处自然条件特殊 ,通天桥工程设计打破了传统桥梁型式 ,采用空间预应力索桥结构 ,该桥型是充分利用现代高强度材料 ,创造性地将主要承重构件按照单一受拉构件进行设计 ,从而形成了一种全新概念的桥梁。以通天桥工程施工为载体 ,介绍空间预应力索桥上部结构施工技术。The spatial prestressed cable bridge is used for Tongtian Bridge, unusually diffarent from the conventional bridge type due to the restrictions of the natural conditions at the bridge site. The bridge is designed in a way of fully using the present high strength materials to make the principal carrying elements on the bridge work as the tensile elements only, thus producing a bridge type of completely new concept. In this paper, construction techniques for the superstructure of the bridge are described.
