本文讨论大跨度预应力混凝土梁桥监测监控过程中,有线形监测、应变测量、支架体系监测、砼裂缝预防监测等方面的技术问题。研究施工过程监控技术体系和组织结构,分析测试应力的诸多影响因素,对确定实际结构的真实应力,桥梁安全施工等具有一定的指导意义。 This article discusses the technical problems in the monitoring and monitoring of long-span prestressed concrete girder bridges, such as linear monitoring, strain measurement, stent system monitoring, concrete crack prevention and monitoring. It is instructive to study the monitoring technology system and organizational structure of construction process and analyze many influencing factors of test stress to determine the real stress of actual structure and the safety construction of bridge.
