中文摘要：

以福建永定土楼中的九盛楼（方形）及侨福楼（圆形）为研究对象，采用ANSYS有限元软件，对土楼夯土结构建立整体模型，并通过数值模拟对两种典型的土楼进行对比分析。结果表明：夯土墙体的最大应力在材料实测的峰值应力以下，其结构强度符合要求；圆形土楼的位移和应力随厚度均匀分布，夯筑形式更加合理。同时，分析夯土结构的薄弱部位，为土楼的加固和维护提供依据。

英文摘要：

Using the finite element software ANSYS,the overall structure models of the Tulou rammed earth square Tu-lou of Jiu-sheng and Circular Tulou of Qiao-fu in Yongding County were established and simulated numerically.The simu-lation results show that the maximum stress of rammed earth wall is under the measured stress peak of the material,its structural strength meets the performance requirements;in circular Tulou,the distribution of stress and displacement va-ry uniformly with the thickness of wall,indicating that the circular form is more reasonable.The weak parts of the Tulou rammed earth structure are point out,to strengthen and maintain of the Tulou.
