AI Technical Summary
The existing prefabricated cantilever retaining walls lack systematic parameter design and stress calculation methods in the design of anchor bolt supports, resulting in overly conservative designs or insufficient strength, which limits their large-scale promotion. Furthermore, the construction process relies on temporary supports and a large amount of wet work, affecting construction efficiency and safety.
This paper provides a design method for anchor bolt supports of prefabricated cantilever retaining walls. Through systematic and refined parameter calculations of shear and tensile-bending design, including precise docking of angle steel, shear keys and shear grooves of the anchor bolt supports, dry mechanical assembly is achieved, reducing on-site wet work and temporary supports.
This achieves a balance between the safety and reliability of anchor bolt supports and the economy of materials, shortens the construction cycle, improves construction efficiency and safety, and reduces material waste and construction costs.
