下承式系杆拱桥施工监控过程中索力的测试与调整

Test and Adjustment of Cable Force in Construction Supervision of Through Bowstring Arch Bridge

在系杆拱桥施工过程中,吊杆索力的大小直接影响着成桥线形及结构的内力分布。为此,在施工监控过程中,应对吊杆索力进行精确测试与调整。现结合实际工程,对常规索力测试方法进行改进,并介绍调索方法,以期对同类工程有所借鉴。

The suspender cable force in the construction of bowstring arch bridge will directly affect the alignment of bridge completion and the internal force distribution of structure.The suspender cable force should be accurately tested and adjusted in the construction and supervision.According to the practical projects,the article introduces the improvement of common cable force test method and the adjusting method of cable in order to be referred for the similar projects.
