Analysis of Construction Technology of Concrete Suspension and Cast-in-Place for High Pier Steel-Concrete Composite Beam Bridge Pavement
Steel-concrete composite beams resist the deflection of the beam body through the joint force of steel beams and concrete bridge decks.They have advantages such as small cross-sectional size,light self weight,large span,strong bearing capacity,low steel and concrete consumption,and short construction period.In this paper,tak-ing the approach bridge of Jianshangou Super Large Bridge as the research object,in order to overcome the unfa-vorable factors of traditional support method construction such as limited construction space,difficult support instal-lation,and high construction safety risks in high mountain and canyon environments,the stress characteristics of steel-concrete composite beams are analyzed in depth,and the innovative use of suspension method for cast-in-place paving concrete is proposed for reference in similar projects.
