斜拉索垂度对大跨度斜拉桥的影响分析

Analysis of Influences of Diagonal Rope Sags on Large Span Cable-Stayed Bridge

大跨度斜拉桥在设计过程中必须考虑斜拉索垂度对结构的影响.以苏通大桥设计方案为背景,分析了在成桥阶段斜拉索垂度引起斜拉索弹性模量的变化.明确了斜拉索垂度影响斜拉桥内力与变形.

In the design process of large span cable-stayed bridge, the influences of diagonal rope sags on the construction must be taken into account. Based on the design plan of Su Tong bridge, this paper analyses the variations in elastic moduli by diagonal rope sags in the stage of finished bridge, and formulates the influences of diagonal rope sags on the internal force and deformation of the stayed-cable bridge.
