四拱肋三系梁钢管混凝土拱桥设计与施工

Design and Construction of Four-rib Concrete-filled Steel Tubular Arch Bridge

慈城大桥是杭州湾跨海大桥南岸接线工程跨越慈江的一座下承式钢管混凝土系杆拱桥,桥梁采用四榀拱肋三系梁设计。通过设计计算和监测桥梁施工过程表明,系梁钢束张拉与吊杆索力是四拱肋三系梁钢管混凝土拱桥桥梁的成桥状态重要控制因素。

CiCheng bridge is a steel concrete bowstring arch bridge which crosses CiJiang south coast by wiring project in Hangzhou bay sea-crossing bridge project.It is designed by the application of four-rib bridge.On the basis of analysis and construction control,the tension of pre-stressed reinforcement of tie beam and skip stretching force is the important step of the construction course.
