摘要
结合云南省景洪市神秘谷澜沧江大桥索塔构造复杂、截面多变、斜率大等特点,详细介绍了劲性骨架结构形式的选取原则、设计控制要点、制作和安装工艺等,在考虑节段混凝土和模板自重荷载作用下验证了斜拉桥索塔劲性骨架设计与施工方案合理可行、安全可靠、经济高效。
Combined with the characteristics of Lancang river bridge in the mysterious valley of Jinghong City,Yunnan Province,such as complex cable tower structure,variable cross sections,large slope,the selection principle,key design points,fabrication and installation process of the stiff frame are introduced in detail.Considering the load of segmental concrete and the formwork,the design and construction scheme of cable tower stiff skeleton of cable-stayed bridge are verified to be reasonable,safe,and economical.
