摘要
结合永川长江大桥南岸边跨现浇箱梁索道管定位的工程实践,从现浇端索道管坐标的计算和修正方面对斜拉桥现浇梁端索道管定位精度控制进行了分析,指出混合梁斜拉桥现浇端索道管的精确定位影响着成桥的斜拉索和线型,对全桥精度控制意义重大。
Combining on the engineering practice of cableway tube positioning on cast-in-site girder for south half of Yongchuan Yangtze River Bridge,the paper analyzes the accuracy control for the positioning of cable on cast-in-site girder end for hybrid girder cable-stayed bridge,and in-dicates the accuracy positioning of the cableways of the bridge can affect the stay cables and its line types of the bridge,so it is important for the accuracy control of the whole bridge.
