【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.更多还原

【Abstract】 Using the finite element software ANSYS,the overall structure models of the Tulou rammed earth square Tulou of Jiu-sheng and Circular Tulou of Qiao-fu in Yongding County were established and simulated numerically.The simulation 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 vary 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.更多还原
