Abstract: In allusion to SuTong dridge’s condition of deep water and rapid flow，This paper summarizes a character giving up traditional steel pipe stake supporting flat rod，using steel canister as supporting component directly and using cantilever orientation guide frame to construct plat roof．This character has paid important role to ensure bridge quality and shorten time limit for the project．

Key words: Sutong bridge, drill fiat rod construction, steel canister

摘要： 笔者针对苏通大桥水深流急的工况，总结了该桥施工时放弃传统钢管桩支承平台方案，直接利用钢护筒作为 承力构件，通过使用悬臂式定位导向架进行平台施工的这一特点，为保证该桥质量，缩短工期提供了重要条件．
