预应力混凝土连续(刚构)梁桥线形监控探索

Exploration of Linear Monitoring of Prestressed Concrete Continuous(Rigid Frame) Beam Bridge

悬臂灌筑预应力混凝土连续(刚构)梁桥是广泛应用于铁路、高速公路、市政工程的一种桥型,通过对已建成桥梁施工过程的模拟计算和悬臂浇筑桥梁的施工监控数据分析,明确了施工立模标高数据来源,用以指导悬臂浇筑桥的梁线形控制,取得了理想的桥梁线形。

Cantilever casting of prestressed concrete continuous （rigid frame） beam bridge is a bridge type widely used in railway, high-speed railway and municipal engineering. Through simulation calculation about the construction process of completed bridge and the data analysis on construction monitoring of cantilever casting bridge, the data sources of construc- tion template elevation is confirmed to guide the linear control of the cantilever casting bridge, and the ideal bridge align- ment is achieved.
