向家坝升船机筒体为薄壁型结构，易在温度、自重、风力等影响下产生变形。为了保证升船机筒体混凝土施工安全及相关金属结构埋件及设备的安装精度，需要对筒体结构变形进行仿真计算预测。介绍了仿真的计算程序、模型及边界条件。比较了计算结果与观测数据，二者基本吻合，但存在局部差异。分析了产生差异的原因，包括，仿真计算未考虑定期联测后基点数据的更新以及结构过水时水汽的影响等。为今后仿真计算的不断完善提供了有益的参考。

The tube of Xiangjiaba ship -lift is a thin-wall structure, and the deformation will occur under the influence of temperature , dead weight and wind .To ensure the construction safety of the concrete and the installation accuracy of metal struc -ture and device, the simulation calculation is conducted to predict the deformation of the tube structure .The program, model and boundary condition of the numerical simulation are introduced .The comparison shows that the calculated results are consistent with the measured ones basically , except some slight difference at local parts .The analysis shows that the ignorance of data up-date of the basic point in regular combined survey and the influence of water vapor in water -filling of the structure cause the difference .
