平转体施工必须保证转体上部结构在转动过程中的平稳性，尤其是大型悬臂结构且无斜拉索情况，在理论上保证其两端达到平衡状态。但是在从设计图纸到结构实体的操作中，由于存在施工可能引起的例如混凝土浇注误差、牵引索布置误差及转体牵引力输出不稳定等影响因素，因此，转体实施前通过把实体结构转换为力学模型进行受力分析检算，进而对转体结构进行平衡称重和配重，就显得非常重要。,flat twist twist the upper structure construction must ensure that the process of ting the smooth, especially the large cable-stayed cantilever structure and no situation, in theory, ensure both ends of the equilibrium. However, the structure from the drawing board to the entity’s operations, because of construction such as concrete pouring may cause the error, set error and twist Sorbian traction traction output instability and other factors, therefore, before the implementation of twist into the structure by the entity Checking the mechanical stress analysis model, and then twist the structure of the balance weight and weights, it is very important.
