The pylon design of long gang bridge in Han zhong is the he three pylons cable-stayed and self anchored suspension bridge,the span is 25 m +90 m +2 ×162.5 m +90 m +25 m.The main bridge with “leap”for the concept,“H”type hollow thin-walled tower is used in the pylon,and is rein-forced concrete structure.Pylon anchorage zone of the “#”prestressed reinforced to balance the horizontal component of cable.This paper introduces the conception of pylon landscape modeling,on the pylon struc-ture,structure design,calculation and analysis of local stress in Anchorage Zone of the conclusion are in-troduced.
