摘　　要：我国采用转体施工工艺的桥梁日益增多,转铰是实现其转体功能的关键结构。目前桥梁平转法施工中转铰一般采用球铰和平面铰,球铰运用比较广泛,而平面铰主要运用于轻型桥梁。本文从转铰结构设计、制作安装、转体施工等方面对两种转铰进行对比分析,论证了平面铰的受力特性和使用性能更加合理。Bridge rotation construction is commonly used to date. Hinge is the key structure. Currently,plane hinge and spherical hinge are both used. The latter is more widely applied while the former is mainly used in light bridge. In this paper,these two hinges were compared in terms of hinge structure design,fabrication,installation,and rotation construction. In this case,plane hinge outweighs spherical hinge in terms of mechanic characteristics and operation properties.
