摘要
对预制空心板、T梁、小箱梁从结构受力、施工工艺等进行多种拼接方案比选,得出各类预制桥梁较为合理的拼接方式。并结合实际工程,计算拼接前后桥梁受力情况,验证了拼接方案的可行性。最后对影响拼接后新旧桥受力性能和耐久性的关键技术进行分析并提出了相应处理措施。
This paper focuses on the research of hollow slab,T beam and small box girder bridge,from the force structure and construction technology for a variety of splicing schemes,concluded more reasonable splicing methods of precast bridges. Combined with practical engineering,the force of the bridge before and after splicing is calculated. At last,the key technologies of the influence of the new and old bridge after splicing are analyzed and the corresponding measures are put forward.
