摘　　要：通过集中力和均布力作用下地基中附加应力的计算,分析了深度和水平距离对集中力作用下地基中附加应力的影响,计算了矩形面积在均布荷载作用下地基中不同位置处附加应力的分布.结果表明,集中力作用下地基土中的附加应力存在最大值,均布荷载作用下矩形面积内的附加应力随着深度增加而下降,矩形面积外的点的附加应力随深度的增加先增加后减少,存在最大值.Through concentration and uniform foundation under the force of additional stress calculation,the influence of depth and horizontal distance on additional stress of the ground was analyzed under concentrated force.The additional stress distribution of the rectangle area under uniform load additional soil at different locations was calculated.The results showed that the foundation soil under concentrated force of the additional stress there is a maximum,when uniformly distributed load the additional stress of the points in the area of a rectangle decrease with depth increasing,the additional stress of points outside the rectangle area increase which there is exist maximum with depth .
