Study on Scheme Comparison and Construction Key Points of No.0 Block Bracket of Large-span Continuous Beam
The No.0 block of large-span continuous beam usually chooses the support methods such as landing support and pier-side bracket according to the pier height and structural size.It is necessary to ensure that the support of No.0 block has sufficient bearing capacity and stability,and to make the support economical and easy to construct.Based on the construction of No.0 block support of(75+130+75)m continuous beam of a highway,through on-site environmental investigation and analysis,comparison and selection of three landing support schemes and modeling analysis of the optimal scheme,the strength,stiffness and stability of the scheme support scheme design are ensured to meet the requirements of the specification,and the effective implementation of the scheme and the quality of the project are ensured.It can provide reference for similar projects.
