摘　　要：选用圆形土楼“庚庆楼”作为拟静力试验的原型,采用材料力学性能与夯土接近的C5混凝土,并分别制作墙厚为80、100和120 mm的圆形土楼缩尺模型.对缩尺模型进行位移控制加载,分析其位移、应变和裂缝变化.绘制滞回曲线并对结构进行耗能能力分析.试验表明:随着圆形土楼墙厚的增加,其刚度、耗能能力、极限承载力以及抗震性能均有一定程度的提高.The circular Tulou(earth building)of“Gengqinglou”was selected as the prototype of the quasi-static test.The C5 concrete with the mechanical properties similar to that of the rammed earth was used to make three scale models of Tulou with wall thicknesses of 80,100 and 120 mm,respectively.Displacement control load was applied to the scale model,and the displacement,strain and crack change were analyzed.The hysteresis curve was drawn and the energy dissipation capacity of the structure was analyzed.The test shows that with the increase of the wall thickness,the stiffness,energy dissipation capacity,ultimate bearing capacity and seismic behavior increase to a certain extent.
