Abstract: The construction method of full space support，which cant satisfy the construction needs of fiaduct with tall piers， is replaced by the construction method of truss frame platform.The beam may be constructed on the truss frame platform which is well both in economy and in safety along the span one by one．Moreover，the truss frame platform can be used as the hanging basket in the cantilever construction，as the climbing formwork in the construction of bridge pier and as the bridge erecting machine in construction of the simply-suppoaed beam bridge．

Key words: full space suppot, truss frame platform, viaduct with tall piers, hanging basket

摘要： 满堂支架施工方法已无法满足高墩高架连续梁桥的施工，代之的是架空平台施工，架空平台采用逐跨推进施 工，经济性和安全性好，此外，该平台还可以作为悬臂施工的挂篮，墩柱施工的爬升模架及用于架设简支梁桥的架桥 机．
