楠溪江大桥施工监控技术探讨

Discussion of Nanxijiang bridge constructing and supervising skill

讨论了楠溪江大桥的监控全过程,包括线型监测、应变测量等方面的技术,阐述了施工预拱度控制和应变测试原理及方法,分析了测试应力的诸多影响因素以及如何控制桥梁的线型、合拢段的相对标高,对同类桥梁的施工及安全使用具有一定的指导意义。

This paper describes the whole process of the construction control for Nanxijiang bridge, including alignment survey and strain-gauging etc. It describes construction camber control, and principle and methods of strain-gauging, analysis some infection factors of test stress. It is hoped to provide important reference for construction and safety transportation of the same kind bridge.
