Structural Design and Checking Calculation of Active Pull Rod V-shaped Pier and 0# Block Support
Prestressed concrete V-shaped rigid frame bridge has the appearance characteristics of beautiful lines and shapes,and can be integrated with the environment.It can reduce the negative bending moment of the pier top girder and reduce the calculated span.Based on the construction of V-shaped bridge and 0# block of Meishan waterway cross-dike bridge,this paper innovatively designs the structure of active rod-type V-shaped pier and 0# block temporary support.This structure can independently balance the horizontal component force generated by the components,make the support structure more stable,reduce the engineering quantity and improve the construction efficiency.On this basis,the article puts forward the checking method and checking results of the V-shaped pier with active tie rod and the temporary support structure of 0# block,which further verifies the rationality of the structural design.
