Dapeng Pedestrian Bridge

深圳大鹏人行天桥设计

The middle-upper Proterozoic  is also called stromatolite. It is famous for its unique standard layer shape. Stromatolite is a special type of paleontological fossil deposited by paleontology mainly composed of cyanobacteria; its diameter ranges from less than one centimeter to several tens of centimeters, and its height ranges from several centimeters to several meters. There is a geological history of 8 to 1.8 billion years ago. The stone is hard, with clear texture and colorful patterns; it truly records the evolution history of the ancient epoch, and stores a large amount of natural information such as paleogeography, paleo-climate, paleo-environment, paleo-structure, paleomagnetism, etc

鱼 鹏 鲲 水 城墙 天空

记忆如海浪般在桥面翻卷

这是我们对过去的怀念

对未来的期许

对历史文化的传递

限定的天空似如翻转的海洋

人如同鱼儿、飞鸟一般

或是栖息停留 或是流动经过

每个人在这里都有属于自己的位置

 

The design of the bridge body is inspired by Kunpeng, which looks like a fish from the side and a wing from the front. Far view pedestrian bridge, bridge

The body is like a fish going out of the water; and the bridge body's façade is based on the tendency of the wings to hug in front of the Dapeng spreading its wings.

to. Along the mountain and sea axis of Dapengsuo City, when people pass through the wings of Peng, they also crossed six hundred

Years of history ushered in a Dapengsuo city that will now spread its wings again.

 

桥身形式的设计灵感源于鲲鹏,侧看为鱼,正看为翼。远望人行桥,桥身如越出水面的鱼;而桥体立面取大鹏展翅前,双翼合抱的趋势为意向。沿着大鹏所城的山海大轴,当人们从鹏之翼穿过时,亦穿越了六百年的历史,迎来一座如今将再次展翅的大鹏所城。

人行桥整体结构为简支梁受力体系,主梁为一个宽11m高2.0

米,跨度为41米,其形式为混凝土预应力简支箱型梁结构体

系。 具体截面设计参照标准40米跨预应力简支箱型梁。 桥墩

采用混凝土重力桥墩,形式采椭圆混凝土异型截面,其上并

安装有4个JPZ盆式橡胶支座。其基础为混凝土承台,桩基础

至地下20米花岗岩持力层。

在人行桥的翼型曲面外立面上,结构采用了202个竖向曲面梁

单元,其材料为30mm厚钢结构板材,通过202个节点,焊接

和锚固混合形式固定在桥面板上。这些钢梁之间使用钢性的

杆件进行横向连接,以保持横向稳定性。

栏杆扶手为高度1.2米的预制不锈钢扶手单元,使用预埋件与

混凝土主梁相连。扶手部分使用橡木扶手等自然材料,并考

虑到无障碍设计规范,设置两个扶手高度供儿童及所需人群

使用。

后续设计工作,对于整个简支梁桥,利用MIDAS进行有限元

分析,进行桥梁挠度和应力分析,地震、当地风荷载的组合

受力分析,桥梁的自振频率的分析,调整和优化截面以满足

正常使用极限状态和国家城市人行天桥(CJJ69-95)规范。

 

The overall structure of the pedestrian bridge is a simply supported beam bearing system, and the main beam is a width of 11m and a height of 2.0 Meters, the span is 41 meters, and its form is a concrete prestressed simply supported box beam structure system. Reference drilling ZK3 The overall structure of the pedestrian bridge is a simply supported beam bearing system, and the main beam is a width of 11m and a height of 2.0 Meters, with a span of 41 meters, in the form of a concrete prestressed simply supported box beam structure system. The specific section design refers to the standard 40-meter-span prestressed simply supported box girder. Bridge pier Concrete gravity bridge piers are adopted, with elliptical concrete special-shaped cross-sections, and There are 4 JPZ basin rubber bearings installed. Its foundation is concrete cap, pile foundation The granite bearing layer is 20 meters underground. On the wing-shaped curved facade of the footbridge, the structure uses 202 vertical curved beams The unit, whose material is a 30mm thick steel structure plate, passes through 202 nodes and is welded It is fixed on the bridge deck in a mixed form with anchoring. Between these steel beams The rods are connected laterally to maintain lateral stability. The railing is a prefabricated stainless steel handrail unit with a height of 1.2 meters, using embedded parts and The concrete main beams are connected. The handrail part uses natural materials such as oak handrail, and consider Taking into account the barrier-free design specifications, two handrail heights are set for children and the people needed use. Subsequent design work, for the entire simply supported beam bridge, use MIDAS for finite element Analysis, analysis of bridge deflection and stress, combination of earthquake and local wind load Force analysis, analysis of the natural frequency of the bridge, adjust and optimize the section to meet Normal service limit state and national urban pedestrian bridge (CJJ69-95) specifications.
