广东虎门二桥坭洲水道桥为主跨1688m 双塔非对称式两跨连续钢箱梁悬索桥，为世界上最大跨径的钢箱梁悬索桥，索塔采用门式钢筋混凝土结构，塔高260m，由下塔柱、下横梁、中塔柱、中横梁、上塔柱、上横梁组成。介绍了该桥索塔的设计思路和构造特点，并采用 MIDAS CIVIL 2012专业桥梁分析软件建立全桥三维空间杆系有限元模型，对索塔结构进行计算，结果表明塔柱及横梁的应力、强度均满足规范要求。

Nizhou Watercourse Bridge is an asymmetric continuous steel box girder suspension bridge with twin towers and a main span 1688m,which marks the largest span of steel box girder suspension bridge in the world. The pylons of the bridge are designed as the reinforced concrete structures with lowerlegs,lower tie beams,middlelegs,middle tie beams,upperlegs and upper tie beams,which contribute a total height of 260m. After presenting the design idea and structure characteristics of the pylon,in the paper,by means of the bridge comprehensive program MIDAS CIVIL 2012, the 3D frame structure finite element model for the whole bridge has been established,and the pylons structure has been calculated. The results show that the stress and strength of the pylons and the tie beams can meet the specifications re-quirements.
