宿迁运河湾半岛玻璃人行斜拉桥设计要点分析

Analysis on Design Essentials of Glass Pedestrian Cable-stayed Bridge on Canal Bay Peninsula in Suqian

摘要:

随着社会发展，公众对美的要求越来越高。以功能为主、兼顾美观的传统桥梁设计原则逐渐转向功能与美观并重。以宿迁运河湾半岛玻璃人行斜拉桥为例，介绍了前倾式独塔玻璃人行斜拉桥建筑造型特点、结构方案、构造细节与施工方案。桥梁跨径布置为135 m+35.5 m，桥塔、主梁均采用钢结构，结构采用塔台固结、梁台固结、塔梁分离体系，拉索采用双索面布置，桥梁主跨跨中设置8组玻璃桥面。建立桥梁空间有限元模型，经验算，桥梁结构受力满足规范要求。目前该桥运营状况良好，达到预期目标。

Abstract:

With the development of society, the public's demands for beauty are getting higher and higher. The traditional bridge design principles that prioritize functionality and aesthetics are gradually shifting towards a balance between functionality and aesthetics. Taking the glass pedestrian cable-stayed bridge on the Suqian Canal Bay Peninsula as an example, the architectural modeling features, structural scheme, construction details and construction schemes of the forward-leaning single-pylon glass pedestrian cable-stayed bridge are introduced. The layout of bridge span is 135 m+35.5 m. The bridge pylon and girder are all steel structures. The structure is composed of the pylon and abutment concretion, the beam and abutment concretion, and pylon and girder separation system. The double-plane layout is used for the stayed cable. Eight sets of glass bridge decks are set at the middle of the main span. By establishing a finite element model of the bridge space, the calculation shows that the force of the bridge structure meets the requirements of the code. At present, the operation of this bridge is in good condition and the expected goal has been reached .
