摘要
预应力混凝土连续梁桥在我国公路、铁路等公共交通建设中得到了广泛的应用。鉴于其施工过程复杂,桥梁结构的应力和线形等受施工影响明显,因此为确保施工过程及成桥运营后桥梁的结构安全、线形良好,需对施工过程实施全程监控。结合某山区预应力混凝土连续梁桥的施工监控,分别对主梁的挠度、应力等进行量测和控制,通过施工监控的实施保证了该大桥在施工及成桥阶段结构的安全,也确保了桥梁的施工质量。
Prestressed Concrete Continuous Beam Bridge Construction is widely used in the aspect of highway, railway and etc. public transport construction of our country, in view of the complexity of construction, the stress and linear of bridge construction is deeply affected by construction, therefore, in order to ensure the safety and good linear during the construction process and after the bridge~ operation, a whole - process monitor on the construction process is necessary, the measure and control on the deflection and stress of girder is conducted respectively. Through the implementation of construction monitor to ensure the bridge＇s structure safety in the phase of construction and finished bridge, and the construction quality of bridge is also ensured.
