摘要
以门善大桥为例,探讨了高墩预应力混凝土连续刚构桥施工控制,首先建立有限元仿真分析模型,对施工阶段及成桥阶段的挠度、内力及稳定性进行定量分析;其次对施工现场的实测数据与理论计算值进行对比分析,掌握桥梁实际施工状态,确保桥梁施工质量与安全.
Take the Menshan bridge for an example, a high pier prestressed concrete continuous rigid frame bridge construction control is discussed in this paper.The finite element analysis model is established first, A deflection of the bridge and internal force and a stability of the phase are analysis quantificationally during construction stages and whole bridge. And next compared the measured data with the theoretical calculation value, bridge construction states are controlled and the bridge construction quality and safety are ensured.
