预应力混凝土连续箱梁桥施工监控

预应力混凝土连续箱梁桥施工过程中会出现复杂的结构体系转化过程,为确保施工过程中的安全及成桥阶段的线形良好需对桥施工过程进行监控。结合巴东罐子口大桥的施工监控情况,针对高程、应力、温度三方面实施测量控制,探讨了预应力混凝土连续箱梁桥悬臂法施工监控情况,通过建立系统的监控过程,采取有效的监控方法保证了罐子口大桥施工期间的安全及最终成桥阶段结构的稳定。

Construction Monitor to Continuous Box Girder Bridge of Pre-stressed Concrete

Complex structural system transformation process in the construction of continuous box girder bridge of pre-stressed concrete will occur,so the bridge construction process shall be monitored in order to make sure the safety and well linear at completion stage.The cantilever construction monitor condition of continuous box girder bridge of pre-stressed concrete are discussed by conducting measure controls to height,stress and temperature combined with construction monitor condition of Badong Guanzikou Bridge...
