1, key points of curved bridge design:
Curved bridge refers to the structural form of bridge transition between straight section and curved section, usually in the form of curved plate, and its length is determined according to the radius of curved section. The linear design of curved bridge should meet the requirements of design speed, curve radius and overtaking lane width to ensure the safe passage of vehicles.
2, bridge structure selection:
The structural selection of curved bridge should be determined according to the actual situation. Common structural forms are simply supported beam, continuous beam and rigid frame bridge. Structural selection should consider the mechanical characteristics and construction difficulty of curved bridge to ensure the stability and economy of the bridge.
3, construction technology and methods:
The construction technology of the bridge mainly includes the steps of foundation treatment, bracket installation, plate beam pouring and bracket removal. In the process of slab beam pouring, it is necessary to control the pouring speed and temperature of concrete to ensure the quality and strength of the bridge. In the process of construction, effective safety measures need to be taken to ensure the safety of construction personnel.
4. Relevant codes and standards:
Bridge construction needs to follow relevant codes and standards, such as Code for Design of Highway Bridges and Code for Construction and Acceptance of Highway Bridges. In the design and construction of bridge bends, it is necessary to refer to these codes and standards to ensure the quality and safety of bridges.
5. Reference:
To learn more about bridge crossing, you can refer to relevant engineering construction manuals, academic papers and professional course textbooks. Professional organizations and associations related to bridge engineering are also important sources of information and experience sharing.
Bridge-bridge bending refers to the adoption of specific design and construction methods in bridge engineering to make the bridge adapt to the curved road curve and ensure the smooth passage of vehicles.
The main bridge crossing is a complex project, which needs reasonable planning and operation in design, type selection and construction. Through reasonable design and construction, the stability and safety of the bridge in curved sections can be ensured, and the smooth passage of vehicles can be ensured.
