Design and Selection of the Supporting System for Cast-in-Place Construction of Long Cantilever Capping Beams
This paper discusses the construction strategy of the new large cantilever viaduct in the central reserva-tion of the existing national highway in Wenling City,and proposes two targeted construction schemes:door-like scaffold and no-floor support system.The advantages and disadvantages of the two schemes are given through structural system analysis,cross-section design and finite element simulation.The door-like scaffold has large stiffness,but it will squeeze the ground access ability;the no-floor support system has larger deformation,but it does not affect the ground access.Duning the actual construction,the engineers can flexibly choose the most suit-able construction plan according to the actual site conditions.
