下承式钢管混凝土系杆拱桥施工监控概述

Overview of Construction Monitoring and Control for Arch Bridge with Lower Supported Steel Pipe Concrete Tipe

桥梁施工监控是保证桥梁建设安全可靠的重要环节。施工监控的目的是要对成桥目标进行有效控制,修正在施工过程中各种参数误差对成桥目标的影响,确保成桥后结构内力和线形满足设计要求。系杆拱桥结构复杂,施工工序多,对施工的要求较高。系统的分析系杆拱桥的施工监控过程对以后的工程具有良好的借鉴意义。

Construction monitoring and control of bridges occupies an important position to guarantee the bridge construction safe whose purpose is to control the goals to finish a bridge efficiently,correct every kinds of parameter errors which influences the goals in the process of construction,ensure that internal force and linear of the finished bridge satisfies the design requirements.The structure of tied arch bridge is complex,the construction process is too much,the requirements to the construction is too high.System analysis on construction control process of tied arch bridge are good for future projects with good reference.
