目的 通过有限元软件分析砖垛无托盘打包结构的安全性与可靠性。方法 对砖垛静置状态和转移状态进行理论分析和有限元模拟。将SolidWorks中建立的模型导入Ansys Workbench进行分析，得到有限元模型。通过施加不同载荷和不同的约束条件得出仿真结果。结果 砖垛在只受载荷静置时，砖垛最大应变、应力集中在从下而上叉车孔所在上层的砖垛第2层；砖垛在转移过程中，砖垛最大应变、应力仍集中在该位置，并产生了挤压与压碎的趋势；捆扎带在砖垛转移过程中，最大形变集中在砖垛底面中心处和竖直方向靠近叉车孔位置。捆扎带的受力已达其许用值的41.2%。结论 在该种打包方式下，砖垛虽然在叉车孔位置处出现横向挤压的破碎趋势，但并未超出砖块的强度范围；捆扎带依旧在许用范围中，能够满足该种打包和堆码方式的需求。

The paper aims to study the safety and reliability of the pallet-free brick stack packaging structure with finite element software. Theoretical analysis and finite element simulation of static state and transition state of the brick stacks were carried out. The model created in SolidWorks was imported into Ansys Workbench for analysis to obtain a finite element model. The simulation results were obtained by applying different loads and different constraints. When the brick stack was placed under static load, the maximum strain and stress of the brick were concentrated on the second layer of the bricklayer from the bottom of the forklift hole; during the transfer process, the maximum strain and stress of the brick were still concentrated at this bottom, and the tendency of extrusion and crushing was generated; during the transfer of the brick stack, the maximum deformation was concentrated at the elevation of the bottom of the brick and the vertical direction was close to the forklift hole. The stress of the strapping tape reached 41.2% of the allowable value. In this kind of packing mode, although the brick stack has a tendency of lateral extrusion at the position of the forklift hole, but it does not exceed the strength range of the brick. The strapping tape is still in the allowable range. It can still fit the needs of this kind of packaging and stacking.
