大跨单肢矮墩连续刚构桥设计

摘要:

连续刚构桥外形尺寸小,桥下净空大,福州市新建金山大桥主桥采用主跨110m变高度预应力混凝土连续刚构桥,主桥根部梁高5.2m,桥墩采用墩高9.57m的单肢实心墩,介绍了大桥的设计参数、施工方案、计算方法等,对主墩及主墩基础设计进行深度分析,该桥设计合理,为类似桥梁的设计提供一定的参考。

Abstract:

The continuous rigid frame bridge had clear space under the bridge with limited sections. FuZhou City JinShan Bridge is a prestressed concrete continuous rigid frame bridge with variable height sections, which the main span was 110m. The beam height was 5.2 meters at the point of support. The mono-wall pier is 9.75 meters high, with solid section. Through depth analysis for the main pier and its foundation, this paper introdeced the design parameters, construction scheme, and computing methods of the bridge. The design of this bridge was reasonable, and it provided reference for similar bridges.
