摘要
介绍了波纹钢腹板体外预应力箱梁的发展历史、国内外关于波纹钢腹板体外预应力箱梁的研究现状及已经取得的研究成果。分析了波纹钢腹板体外预应力箱梁的结构特点、理论计算方法、与普通预应力混凝土箱梁桥的区别以及在桥梁工程中应用的优势。最后,结合我国实际情况提出这一结构需要进一步研究的问题,包括波纹钢腹板的拼装工艺、与箱梁的剪力连接构造、波纹钢腹板体外预应力箱梁的疲劳性能研究及动力性能研究等等。
The development history, current status and research achievements of externally prestressed box girder with corrugated webs is introduced.The structural character, theoretical calculation method, difference between the externally prestressed box girder with corrugated webs and the prestressed box girder and the superiority of using this structure in the bridge engineering are analyzed.The research of externally prestressed box girder with corrugated webs is also introduced, and the further problems that need to be solved are put forward based on the actual situation in China including the corrugated web installation technology, its shear connection structure, the fatigue and dyuamic performance of the externally pre-stressed box beam and etc.
