浅基础下设变刚度垫层地基应力场模型试验

Model experiment of stress in soil under shallow foundation with variable stiffness cushion

通过室内模型试验，研究浅基础下设变刚度垫层地基土中应力分布、变形性状规律。变刚度垫层的设置，使得基底反力向基底中部集中，并提高了地基极限承载能力。

The stress distribution and deformation properties in soil under shallow foundation with variable stiffness cushion are studied through a model experiment. It shows that, by the variable stiffness cushion, the contact pressure is concentrated toward the center of shallow foundation and the ultimate bearing capacity is also increased.
