| 摘 要： | 结构参数误差是斜拉桥施工控制过程中误差产生的重要来源.为分析结构各设计参数对桥梁成桥状态影响的敏感性,以江津观音岩长江大桥为背景,采用有限元法计算各设计参数对大跨度结合梁斜拉桥主梁成桥线形和主梁应力的影响.结果显示:主梁重量、拉索制造长度、桥面板重量和温差对该桥主梁成桥线形及主梁应力有显著影响；桥面板弹性模量和主梁弹性...

| Abstract: | The errors of structural parameters are the important sources causing the errors in the construction control process of cable-stayed bridge.To analyze the sensitivity of influences of various structural design parameters on the completion status of the long span composite girder cable-stayed bridge,the Guanyinyan Changjiang River Bridge in Jiangjin was cited as an example,the finite element method was used to calculate the influence of each parameter on the geometric shape and stress of the main girder of t... |
