摘　　要：基于明德林解,给出了圆形面积均布荷载作用下,便于制定应力系数表格的竖向附加应力实用理论计算公式。讨论了基础相对埋深对地基中竖向附加应力的影响。所得结论,对改进现行地基应力与变形计算方法具有重要的理论意义和长远的实用价值。Based on the Mindlin's elastic formula, a practical theoretic formula for calculating the vertical superimposed stress under the circular area with uniform distributed loading is presented,which makes the data table easily. The vertical superimposed stress is much influenced by relative depth of foundation.In this paper, some conducting meaningful concepts and views were obtained.It is theoretically and practically important to improve the present method for calculating superimposed stress and foundation deformation.
