三汊矶湘江大桥预应力混凝土箱梁顶推施工

The prestressed concrete box beam incremental launching construction of Sanchaji Xiangjiang Bridge

结合工程实例,分析介绍了长沙市三汊矶湘江大桥东岸边孔预应力混凝土箱梁顶推施工技术方案,从临时设施、梁段顶推、施工监测三方面对顶推施工技术及质量控制措施进行了详细阐述,以指导实践。

Combined with engineering example,the east bank pore prestressed concrete box beam incremental launching construction technical program of Sanchaji Xiangjiang Bridge was analyzed and introduced,it was detail illustrated from temporary facility,beam incremental launching and construction monitoring so as to guide practice.
