This paper presents the model tests and nonlinear numerical analysis of the interaction between bucket founc and soils under vertical loadings. Loading-settlement curves from numerical calculations and from model tests are in. agreement. The variation of vertical load distribution on different parts of a bucket foundation is analyzed, and the coplx sistance distribution along the radius, the skin friction rariation along the depth, and the characteristics of tip resistanc provided. The influence of coping on the load characteristics of bucket foundation and the differencte load characteristic tween bucket foundations and solid foundations are also analyzed computationally. |
