怀阳高速公路广信大桥大跨度斜拉桥施工监控

Construction Monitoring of Long-span Cable-stayed Bridge of Guangxin Bridge in Huaiyang Expressway

依托于怀阳高速公路广信大桥斜拉桥的施工,主要阐述大跨度斜拉桥监控测量技术。主要内容包括:平面、高程基准的设立,主塔位移测量,主梁线形观测,温度、时间与主梁标高关系曲线的选定,观测时段的选择等。

Based on the construction of the cable-stayed bridge of Guangxin Bridge in Huaiyang Expressway,the monitoring and measuring technologies of long-span cable-stayed bridge are mainly expounded.The main contents include the establishment of plane and elevation datum,the displacement measurement of main pylon,the observation of main beam alignment,the selection of the relationship curve between the temperature and time and the elevation of main beam,and the selection of observation period,etc.
