Design and analysis of anchorage zone and deviation block of external prestressed concrete bridge

摘要：

　　As an external prestressed concrete box girder continuous rigid-frame bridge with the longest span in China,the Xiantan Bridge was reported in this paper for its special characteristics.The key points of the end cross beam for anchorage zone and deviation block for the deviator were introduced in detail for its design.The finite element models for them with 3D FEM were created to get the stress state to ensure the safety.Taking the stress distribution results into account,the optimization design for the thickness for these key locations was reported too.The results can provide reference for the similar projects.
