基于温度效应的长寿长江二桥施工期结构响应研究

Study on Structural Response of Changshou Yangtze River Second Bridge During Construction Period Based on Temperature Effect

悬索桥是以承受拉力的缆索或链索为主要承重构件的桥梁,易受环境、温度等因素影响。为了保证良好的施工质量,论文基于有限元模型及悬索桥计算分析系统,对施工期基准索股架设、主索鞍顶推以及主缆线形进行分析和研究,并得出温度影响下的结构响应规律。

Suspension bridge is a bridge with tension-bearing cable or chain as the main load-bearing component. It is easily affected by environmental temperature and other factors. In order to ensure good construction quality, this paper analyzes and studies the strand erection, the main cable saddle push and the main cable line shape based on the finite element model and the suspension bridge calculation and analysis system, and the structure response law under the influence of temperature is obtained.
