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
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.

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.
