| 摘 要： | 以一座四跨曲线梁桥为背景，采用单主梁法建立空间有限元模型，对不同中支座偏心距情况下恒载、活载支座竖向反力进行了计算分析。结果显示，支座反力主要受恒载分配的影响，各种偏心距情况下活载反力变化幅度较小。支座偏心设置方法可用于类似桥梁的设计。

| Abstract: | In this paper, taking a four-span curved girder bridge as the background, a tinite ele- ment model is built using the single beam method, for different bearing eccentricity in case of dead load, live load bearing vertical reaction forces are calculated and analyzed. The results show, the counterforce of the support is mainly affected by the constant load distribution, various eccentricity under live load force of smaller amplitude. Eccentric support this setting method can be used for the design of similar bridges. |
