Taking the extra large round foundation engineering as an example,the paper establishes actual three-dimensional finite element calculation model and parameter selection,and explores three-dimensional numerical simulation of various round foundation excavation mode.Combining with local hydrogeological condition,it points out controlling and design according to foundation deformation,which has guiding meaning for similar engineering construction.
