摘　　要：转体桥梁上跨既有公路、铁路、航道的优势突出,具有安全性好、对运输干扰小的优点,尤其是在跨越铁路时,已经成为首选的桥梁方案。以某独塔单索面混合梁斜拉桥项目为工程背景,对混合梁斜拉桥的钢-混凝土结合段在转体施工过程中的受力进行研究,确保转体过程中结构安全可靠。The advantages of the rotation construction bridge over the existing highway,railway and waterway are outstanding.It is safety and very small interference to the transportation and become the preferred bridge scheme,especially when crossing the railway.Based on the engineering background of a single tower and single cable plane hybrid girder cable-stayed bridge,this paper studies the stress of the steel-concrete joint section of the hybrid beam cable-stayed bridge in the process of rotation construction,so as to ensure the safety and reliability of the structure in the process of rotate.
