Abstract
To improve the efficiency of bridge construction and reduce the impact on the surrounding environment,relying on the construction practice of a bridge construction project,a non-floor support system is proposed,and the theoretical analysis is used to check the mechanical index of each component.The results show that the maximum negative bending moment of the structure is 139.56 kN·m,the maximum shear force is 121.6 kN,and the maximum positive bending moment is 52.5 kN·m,all of which meet the design requirements,indicating the ra-tionality of the support system without floor support.After construction,the overall deformation range of the support system is3～4.5 mm,the maximum settlement at both ends of the main beam is 5 mm,and there are no holes and exposed ribs on the surface of the cover beam.The construction technology has good application effect.关键词
