摘要
将多跨桥梁施工控制的理论应用于沪宁城际轨道交通工程连续梁桥的实际施工过程,对施工期间的线型、应力等内容进行有力地控制和调整。结合施工过程中测得的各阶段主梁应力与变形数据,分析各施工阶段中主梁内力和变形与设计预测值的差异,提出修正对策,以协助施工单位安全、优质、高效地进行施工,并确保在全桥建成以后桥梁的内力状态和外形曲线与设计尽量相符。
By integrating the control theory and the practi- cal construction method of multi-span continuous beam bridge on Shanghai-Nanjing Intercity Railway, the bridge liner and the concrete stress are well controlled and adjus- ted, the actual data and theoretical value are analyzed in combination with the deformation of bridge measured dur- ing the engineering, which will ensure the smooth construc- tion and adjust the stress and liner to the design.
