摘要
扩展式基础的基底反力一般呈非线性分布。数值模拟的结果显示 ,岩石地基上的扩展式独立基础 ,其基底反力分布的非线性特征非常显著 ,并且其分布模式和变化规律与土质地基不同。基础高度 ,即基础与基岩的相对刚度是决定基底反力分布模式的主要因素 ,随着基础和基岩相对刚度从小到大的变化 ,基底反力分布模式从中部集中向接近均匀分布过渡 ,再向边缘集中发展。
The spreading foundation′s base reaction is a nonlinear distribution normally.The result of numerical analysis shows,for the spreading foundation on rock foundation,there has more notable features that the base reaction nonlinearly distributes,and its distribution pattern and change law are different from that on soils.The height of foundation decides the distribution pattern of the base reaction.Along with the increasing of relative rigid from little to great,the base reaction centralizes in central section firstly,then transforms to near even distribution,then centralizes in edge.
