摘　　要：嘉绍大桥主航道桥索塔为带"X"形托架的独柱式结构,其结构新颖复杂、施工难度大。文章介绍了独柱索塔的施工工艺,包括液压爬模施工、钢筋制安、混凝土浇筑、养生等环节的一些有效措施。并就支架设计、塔柱实心段温控、环向预应力等关键技术进行了研究,为今后类似工程提供参考。The main channel bridge of the JiaShao bridge is the single column structure with the ＂ X＂ bracket, its novel structure is complicated and the construction is very difficult.This paper introduces the construction technology of the single pylon, the hydraulic climbing form, the fabrication and installation of rebar, the concreting, the concrete curing and so on. And it studies the key technology of the bracket design,the temperature control for the solid parts and circum prestress. It provides references for the similar engineerings.
