摘要
斜拉桥是重要的桥梁结构形式,由于其梁体内弯矩小、建筑高度低等优点而被广发地采用。该文主要针对大型斜拉桥的空间结构特点,分析和研究了斜拉桥的空间设置和设计问题。首先根据斜拉桥的结构组成,分析了各个组成构件的空间布置,并进行了相应的力学计算,在此基础上,研究了大型斜拉桥的空间结构设计,主要讨论了在具体情况下的结构选型问题。
The cable-stayed bridge is an important bridge structure type,and is widely used because of its small beam moment and low architectural height.Mainly aiming at the space structure characteristics of large-sized cable-stayed bridge,the article analyzes and studies the space setup and design of cable-stayed bridge.Based on the structure combination of cable-stayed bridge,the article analyzes the space setup of various components and carries out the relevant mechanical calculation.On this basis,the article studies the space structure design of large-sized cable-stayed bridge,and mainly discusses the structure selection under the detail condition.
