摘要
就南京龙池立交桥预应力曲线箱梁设计中的关键技术──钢管混凝土的独柱偏心影响、箱梁横隔板的作用及预应力筋的配置进行了计算分析；并介绍了箱梁混凝土的浇注工艺及预应力施工的方法。
Technical cruxes, such as eccentric influence of steel pipe-confining concrete single column,function of diaphragms and arrangement of prestressing tendons in curved box girders, in design of Longchi Prestressed Concrete Overpass in Naming are calculated and analysed. Concreting technology for the box girders and construction method for the prestressing system are dealt with as well.
