非半无限空间均布荷载下地基附加应力的理论计算研究

here are very few practical applications of semi-infinite foundation. Almost all the current methods of calculating foundation superimposed stress actually consider the foundation as an elastic semi-infinite space. In the actual constructions, the load is seldom applied to the foundation in concentrated form, while it is usually distributed to a certain area. This paper provides the formula of superimposed stress of non semi-infinite foundation on distributed load by the image method, based on the J. Boussinesq formula of superimposed stress of semi-infinite foundation on concentrated load. Comparing with the formula of superimposed stress of semi-infinite foundation on superimposed stress, we found that the formula of superimposed stress of non semi-infinite foundation on distributed load is more suitable for the situation of realistic projects.
