摘要
以某座跨越长江的叠合梁斜拉桥为背景,利用有限元分析程序进行计算。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,进而得出了针对叠合梁斜拉桥成桥过程中的参数敏感性的一般性规律,并据此提出了监控意见。
Based on a composite cable-stayed bridge over the Yangtze River, and through the use of finite element analysis program, the paper calculated and compared the impact of various design parameters in the girder line and the girder stress; in addition, analyzed the sensitivity of the design parameters. Then, the paper concluded the regular pattern of the sensitivity of the design parameters while construction and put forward the monitoring advice.
