| 摘 要： | 以江津观音岩长江大桥为背景,利用有限元分析程序BSAS4.24进行计算,通过比较各设计参数在成桥时对主梁线形和主梁应力的影响,分析了各设计参数的敏感性,得出该桥有显著影响的参数主梁重量、拉索制造长度、温度变化,并据此提出了监控意见。

| Abstract: | Based on the Guanyinyan Yangtze River Bridge of Jiangjin, and through the use of finite element analysis program - BSAS4. 24, we calculated and compared the impact of various design parameters in the girder line, the girder stress,in addition, analyzed the sensitivity of the design parameters. We concluded that the main beam weight,the length of cable manufactured,the weight of the bridge deck all have a significant influence while the stiffness of the bridge deck and the main beam bridge have not prominent influence, and accordingly put forward the views of the monitor. |
