Reasonable Structure Design of Main Girder Anchorage of Stay Cable

摘要:

Abstract:

The Nanxi (Xianyuan) Yangtze River Bridge in Yibin is a state-planned key project of the new crossing channel of the Yangtze River trunk line. The asymmetric hybrid girder cable-stayed bridge scheme is adopted for the main bridge with five span 280 m + 572 m + (72.5 + 63 + 53.5) m double tower and double cable plane. The anchor plate structure is selected for the anchorage of stay cables on composite beams. This paper mainly introduces the key technologies of anchor plate structure, including reasonable structure, calculation analysis and main construction points.
