Zhishuigou super-large bridge on Huangling-Hancheng-Houma Railway applies 19 × 64 m +2 × 48 m simply-supported segmental precast box-girders. T hese segments are assembled with epoxy resin instead of the traditional wet joint. Design and construction of Zhishuigou super large bridge are introduced in this paper. T he categorization and application of precast segment,as well as its structure,design,production and advantages,are presented. T hese may be used as guidance for design and construction of the same type bridge.
