摘　　要：泉州后渚大桥处于沿海严重腐蚀的自然环境,据此,在设计中选择合理的结构型式,引进真空辅助压浆,采用PVC波汶管成孔,加厚钢筋保护层,采用钢筋环氧涂层保护以及选用高强高性能混凝土等措施,以提高桥梁结构防腐蚀能力,延长使用寿命。Houzhu Bridge in Quanzhou lies in nature surroundings with serious erosion. In design, therefore, choose the reasonable structure, use the technique of filling cement mortal in vacuum condition, adopt the PVC pipe to make holes, make the concrete cover thicker, adopting the steel with epoxy cover and the high strength concrete and so on. Taking these measures will improve the anticorrosive ability of bridge and extend the life span of structure.
