摘要
结合达陕高速公路王家坝大桥连续刚构桥工程实例,利用ANSYS计算软件建立了该桥最高墩自体施工、最高墩最大悬臂施工和成桥阶段各种工况下的特征值稳定分析,并得出了高墩大跨连续刚构桥施工过程中稳定性的一些规律。
Based on a typical long-span continuous rigid frame bridge with high piers-Wangjiaba Bridge construction, using ANSYS software, the model of the highest pier body construction phase, the model of the maximum cantilever construction phases at the highest pier and the model of the bridge closing phase are established. By comparing with the theoretical calculation, the influence factors of the stability in the bridge construction process are obtained.
