根据弹性半空间理论下附加应力系数的布辛奈斯克解,分别推导出矩形均布荷载、三角形分布荷载下角点和圆形均布荷载下中心点的平均附加应力系数的解析解,通过与《建筑地基基础设计规范》(GB50007-2011)中数据的比较,证明其精度更高,其编程计算比查表更为方便.
根據彈性半空間理論下附加應力繫數的佈辛奈斯剋解,分彆推導齣矩形均佈荷載、三角形分佈荷載下角點和圓形均佈荷載下中心點的平均附加應力繫數的解析解,通過與《建築地基基礎設計規範》(GB50007-2011)中數據的比較,證明其精度更高,其編程計算比查錶更為方便.

@@@@The analytical solution of the coefficient of the average additional stress under the rectangular uniform load,the triangle dis-tributed load and the circular uniform load is de-duced respectively using the Boussinesq solution of the additional stress by the theory of elastic semi-infinite body. Compared with the data of the code for design of building foundation (GB50007-2011),it is proved that the accuracy is higher and the programming calculation is more conve-nient than the look-up table.
