大跨度连续梁桥施工监测控制技术

Technology of Construction and Monitor on Long span Continuous Beam Bridge

以楠溪江大跨度预应力混凝土连续梁桥为例,概述了大跨度混凝土连续梁桥施工控制的目的、内容、方法和措施,论述了楠溪江大桥在施工监控中线形与应力监测的一些理论与方法,经工程实践验证此种方法对大跨连续梁桥的施工监控是可行的,为同类桥梁的施工与监测提供参考。

On the basis of Nanxi jiang long-span prestressed stress concrete continuous beam bridge, the purpose, content and measure of construction control of it is. summarized, theories and methods of monitor of deflection and stress during the construction of it are introduce. It is feasible to use this method to monitor the construction of long-span prestressed stress concrete continuous beam bridge, which is proved by engineering. Some experiment related to construction and monitoring are summarized, which is provided as a preference for similar engineering.
