| 摘 要： | 斜靠式拱桥外形独特、新颖 ,是颇有竞争力的城市景观桥型。但是目前已建成的斜靠式拱桥多为有推力体系 ,不适合我国江浙一带的软土地基 ,本文提出无推力斜靠式拱桥体系 ,并以昆山玉峰大桥为例 ,就其概念设计、力学性能、细部构造、施工过程等关键性技术问题展开讨论 ,旨在使斜靠式拱桥体系的设计得到进一步优化

| Abstract: | The leaning-type arch bridges are novel-looking and thus more competitive for city sights.The leaning-type arch bridges completed thus far are almost systems with thrust,which are unfit for the soft soil foundations in China.This paper presents a system of leaning-type arch bridges without thrust.Using the Kunshan Yufeng bridge as an example,key technical issues such as conceptual design,mechanical characteristics,detailed conformation and erection process,are investigated,in order for the design of the leaning-type arch bridge system to be optimized. |
