过水钢管拱桥施工监控分析

为了控制桥梁建设过程中的安全、进度和质量,需要对全桥建设全过程进行施工监控。本文根据大桥施工过程中各阶段主拱肋标高、轴线偏位、内力(应力)以及拱肋安装过程中缆索吊装系统的变形与内力等监测数据,实时分析实测数据与预测值的差异,确保桥梁施工中的安全和顺利合拢。

In order to control the safety, progress and quality during the process of bridge construction, the whole bridge construction is needed to monitor and control the whole bridge construction.. In this paper, according to the bridge during construction of the main arch rib elevation, axis displacement, internal force （stress） and erection of arch ribs in the process of cable erection system of deformation and internal force monitoring data, real-time analysis of measured data and predicted values differences to ensure bridge construction safety and smooth closure.
