斜拉桥模型的设计与制作

Designing and Building Cable-stayed Bridge Model

斜拉桥是将桥面用许多拉索直接拉在桥塔上的一种桥梁,是由承压的塔,受拉的索和承弯的梁体组合起来的一种结构体系,是现代大跨桥梁的重要的结构形式。斜拉桥模型试验是研究复杂桥跨结构或复杂构造细节的重要手段之一,其目的是为结构分析提供数据和结论,也是检验数值理论和解析理论正确性的主要依据。文中详细介绍了斜拉桥模型结构的设计理论、制作过程及关键工艺。并针对设计和制作等方面的问题作了一定的探讨和研究。

Cable-stayed bridge is constructed by many cables which pull bridge face directly to the bridge tower. This architecture, composed of a stressed tower, pulled cables and bent beams, is an important construction form of modem spanning bridges. The model tests of cable - stayed bridge are an important method in studying complicated spanning structures, aiming at providing data and conclusion for structure analysis. It is also a main criteria for checking correctness of numerical theory and analytic theory. This paper describes the design theory, building process and key techniques in details.
