Inclined single-tower cable-stayed bridge restraint system and design and application method thereof
The invention discloses an inclined single-tower cable-stayed bridge restraint system and a design and application method thereof, and relates to the technical field of bridges. The single-tower cable-stayed bridge restraint system comprises a cable structure tensioned between a tower beam consolidation position and a foundation at the end of a main beam main span through pre-tension, and a thrust structure installed between the tower beam consolidation position and a foundation at the end of a main beam side span through pre-thrust. Or the longitudinal elastic telescopic device is mounted between the side span end part of the main beam and the foundation of the side span end part of the main beam by pre-pressure; the inhaul cable structure or the thrust structure or the longitudinal elastic telescopic device is used for at least partially counteracting unbalanced horizontal force of the stay cable of the single-tower cable-stayed bridge. According to the single-tower cable-stayed bridge restraint system and the design and application method thereof, the unbalanced horizontal force of the stay cable can be at least partially offset, then the bending moment of the lower tower column of the main tower is effectively reduced, the section size of the lower tower column is reduced, the bridge landscape effect can be optimized, bridge design is facilitated, and the applicability of the bridge type is improved.
本申请公开了一种斜独塔斜拉桥约束体系及其设计应用方法，涉及桥梁技术领域，该斜独塔斜拉桥约束体系包括：以预拉力张拉于塔梁固结处与主梁主跨端部的基础之间的拉索结构、以预推力安装于塔梁固结处与主梁边跨端部的基础之间的推力结构、或者以预压力安装于主梁边跨端部与主梁边跨端部的基础之间的纵向弹性伸缩装置；上述拉索结构、推力结构、或者纵向弹性伸缩装置用于至少部分抵消斜独塔斜拉桥斜拉索的不平衡水平力。本申请的斜独塔斜拉桥约束体系及其设计应用方法，可至少部分抵消斜拉索的不平衡水平力，进而有效降低主塔下塔柱的弯矩，减小下塔柱截面尺寸，不仅可优化桥梁景观效果，还利于桥梁设计，增大此类桥型的适用性。
