摘要
介绍了预应力混凝土桥梁节段施工的发展历程及主要方法,探讨了悬臂施工法、逐孔施工法和顶推法的基本原理、力学特点和关键施工技术,可供预应力混凝土桥梁施工参考。
The main sectioned construction methods for pre-stressed concrete bridges and the developing process of the construction are presented in paper, with the basic principles, mechanical characteristics and the key techniques of the cantilever construction method, span-by-span construction method, and the push construction method are discussed. The paper may serve as a reference for similar pre--stressed concrete bridges.
