2.3 Ultimate bearing capacity of shallow foundations(浅基础极限承载力) Foundations can be classified as shallow and deep foundations. In general,if the depth of a foundation (D)is smaller than or equal to its breadth (B),i.e.D/B s 1,the foundation is classified as shallow foundation. 股认为，当基础的理深D 或 于基础宽度B时称为浅基础 Ground Surface 蘭 B (a)Shallow B (b)Deep 2.3 Ultimate bearing capacity of shallow foundations (浅基础极限承载力) ▪ Foundations can be classified as shallow and deep foundations. In general, if the depth of a foundation (D) is smaller than or equal to its breadth (B), i.e. D/B  1, the foundation is classified as shallow foundation. (一般认为,当基础的埋深D 小于或等于基础宽度B时,称为浅基础)
