大吨位平面转体连续梁桥转体施工和监控要点

The Key of Rotatiny Construction and Monitoring on Large-tonnage Plane Rotation Continuous Beam Bridge

桥梁平面转体施工是利用桥梁组成部分为转体结构,将支架预制拼装的梁体旋转安装到位,适用于跨越不间断交通的航道、铁路或公路的桥梁施工。为确保大吨位的平面转体桥转体的安全,转体时应对转体的落架、试转和正式转体中的各种参数进行监测控制。

For the safety of rotation construction,from several aspects,the paper analyzed various parameters of monitoring.
