深圳前海合作区梦海前湾河大桥设计
|
摘要
深圳前海合作区梦海前湾河大桥的设计理念为"护佑之翼",采用一跨简支拱梁组合结构,造型美观,辨识度高,但结构受力构造复杂。通过对该桥总体设计的介绍,论述了项目设计的特点和难点,并阐述了参数化建模在该桥中的运用。同时,对该桥节点处的细节设计、高强超厚钢板的应用、车致振动效应的行人舒适性等方面均提出了相应的解决办法。
The conceptual design of the Menghai Qianwan River Bridge in Qianhai cooperation zone of Shenzhen is "the wing of protection". It adopts a composite structural steel bridge with simply supported arch beam, which has a beautiful shape and a high degree of identification, but its structure is complicated. This paper introduces the overall design of the bridge, discusses the characteristics and difficulties of the project design, and explains the application of parametric modeling in the bridge. Solutions are proposed for the detailed design of joints, the use of high-strength and ultra-thick steel plates, and the study of vehicle-induced vibration effects on pedestrian comfort, so as to provide a reference for the design of similar bridges.
