摘要
为了保证连续梁桥顺利合龙及成桥线形符合设计要求,需要进行桥梁施工线性监测和控制.以新建西成客运专线一座(72+120+72)m连续梁桥为例,运用桥梁软件Midas进行理论计算,并结合现场的监控实测数据,对施工阶段的立模标高进行预测和调整,实现连续梁桥的线形控制.
In order to ensure the smooth closure of the continuous beam bridge and guarantee the design require- ments, it＇s necessary to carry out bridge construction linear monitoring and control. Taking a （72 ＋ 120 ＋ 72） m continuous beam bridge as an example, the bridge software Midas theoretical calculations and on-site monitoring of measured data, the construction stage of the vertical elevation of the forecast and adjustment is performed to re- alize the linear control of continuous beam bridge.
