摘　　要：根据拱型槽板实际变形情况 ,建立了合理的有限元计算模型 ;介绍了利用ANSYS软件对拱型槽板变形的计算过程 ;计算过程中考虑到拱型槽板变形是弹塑性变形 ,得到回弹前和回弹后的变形图。A reasonable finite element model is set up according to the actual deformations of the arched trough plates.The calculation course of the deformations of the arched trough plates using ANSYS software is also introduced,during which the fact that the deformation of an arched trough plate is an elastoplastic one is taken into account,by which the deformation patterns before and after rebound are obtained.
