摘要
桥梁转体施工是在河流的两岸或适当的位置,使用简便的支架先将半桥预制完成,之后以桥梁结构本身为转体,使用一些机具设备,分别将2个半桥转体到桥位轴线位置合龙成桥。论文针对大跨度连续梁转体施工关键技术进行了研究与探讨,希望能为同类转体桥梁施工提供技术支持,促进我国大跨度连续梁桥转体施工水平的提高。
Bridge rotation construction is to prefabricate the half bridge by using simple supports on both sides of the river or at appropriate positions. Then, the bridge structure itself is used as the rotating body, and some machines and equipment are used to rotate the two half bridges to the axis position of the bridge to form the bridge. This paper studies and discusses the key technologies in the rotation construction of large-span continuous girder, hoping to provide technical support for the construction of similar rotating girder bridges and promote the improvement of the rotation construction level of large-span continuous girder bridges in China.
