摘要
以某三跨(20+25+20)m连续梁桥为例,简述了连续梁桥纵向预应力筋的估算方法及计算原理,分别计算了承载能力极限状态、正常使用极限状态下预应力筋的配置情况,最后简要介绍了后张法预应力损失的计算,望能对实际设计、施工有一定的帮助。
Taking a three-span（20 ＋ 25 ＋ 20）m continuous bridge for example, outlines the continuous bridge vertical prestressed steel bars estimation method and calculation principle. The ultimate limit state, serviceability limit state, the configuration of tendons were calculated. Finally a brief introduction of the prestress steel bars loss calculation, hope the paper can be helpful to the actual design and construction.
