瓜亚斯河大桥主桥为208+416+416+208m三塔四索面钢混组合梁斜拉桥。索塔设计为独特的Y形空间刚性结构,采用49根2.5m钻孔支承摩擦群桩基础;由工字钢形纵梁及横梁与现浇混凝土桥面通过剪力钉连接而成钢混组合梁,具有较大的横向刚度和抗风稳定性;斜拉索采用了索梁拉板锚固和索塔耳板销接的锚固技术,并带有调节套筒,便于主桥几何线形的调整。其设计主要特点是桥型美观新颖,便于施工和维护。
The main bridge of the Guayas River Bridge is 208 + 416 + 416 + 208m cable-stayed bridge with steel-concrete composite beam. The pylon is designed as a unique rigid structure with Y-shaped space. 49 2.5m boreholes are used to support the foundation of the friction group pile. Steel girders are formed by connecting the I-beam and the cross beam to the cast-in-place concrete deck through shear nails The composite girder has greater transverse rigidity and wind resistance stability. The stay cable adopts the anchoring technology of the cable girder pull plate anchorage and the pylon ear plate pin, and is provided with the adjusting sleeve to facilitate the adjustment of the geometric shape of the main bridge . The main features of its design is beautiful bridge novel, easy construction and maintenance.
