摘要
在对预应力设计基本要求及布束原则、预应力设计的理论依据及预应力筋布置形式分析的基础上,对大跨径预应力混凝土连续刚构桥的预应力钢束配置进行了研究,通过已建连续刚构桥得出预应力钢束的用量,并通过有限元程序对所得数据进行验证分析,得出了一些规律和结论,可以作为同类桥梁的设计参考。
According to the basic requirements,the tendon-arrangement principles,and the theoritical basis for prestress design,the prestressed tendon arrangement for a long span prestressed concrete continuous rigid frame bridge is analyzed and studies.The needed amount of the prestressed tendon can be acquired from the designs for the completed bridges similar to this one.Some regularities and conclusions are derived from the relevant data analysis and verification by means of the software of the finite element method,and they can be used as reference for the bridge designs similar to this one
