摘　　要：在进行丫髻沙大桥的转体施工方案的计算（ 线性与非线性） 中， 采用的是通用有限元分析程序ＳｕｐｅｒＳＡＰ９３。本文论述了计算某个工况下的内力、应力和位移及调索的过程。计算中用梁元、桁元及间隙元／ 缆索元等多种不同类型的单元共同建模。以更准确地模拟施工过程。In calculation for the rotating cosntruction of YaJisha Bridge (linear and nonlinear), a program for finite element analysis is used, i.e. Super SAP93. Described in this article is calculation of the internal force, stress, displacement and cable adjustment under a certain operation condition. Different elements are applied in calculation to establish the module for more accurate simulation of the construction process.
