摘要
采用数值模拟方法,以福建龙岩的振成楼、承启楼等经典圆形土楼为原型,建立圆形土楼夯土结构模型.对土楼夯土墙体在静力荷载作用下的结构承载性能进行分析,通过改变土楼各尺寸参数,分析不同土楼夯土结构模型的受力及变形特征,得出影响受力变形规律特征的主要因素.结果表明:不论是在墙厚、直径还是墙高模拟中,应力、位移都不是单调变化的,有合理的取值区间.
By the numerical simulation method,taking the classic circular Tulou（rammed earth building）in Longyan,Fujian,such as Zhencheng Tulou,Chengqi Tulou,the circular Tulou structure model was establish.the bearing capacity of Tulou wall was investigated under the static loads.the stress and deformation characteristics of different Tulou structure models were studied for the parameters of various sizes of Tulou,the main factors influencing the stress deformation characteristics were obtained.The results show that for different wall thicknesses,diameters and heights,the stress and displacement do not change monotonously,and it has a reasonable value range.
