摘　　要：以圆形面积均布荷载作用为例,将基于布辛奈斯克解和明德林解所得附加应力相比较,讨论了基础埋深及泊松比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。Superimposed stress and foundation deformation are influenced by depth of foundation and Poisson＇s ratio, taking circular footing with distributed uniform loading as an example, these problems are discussed in this paper. Some conducting meaningful concepts and views were obtained. It is theoretically and practically important to improve on the present method for calculating superimposed stress and foundation deformation.
