| Abstract: | On the basis of three-dimensional finite element method,the lateral friction resistance,the tip resistance and socket length of rock-socketed pile are analyzed and calculated.the influence of the lateral friction resistance on pile capacity,the relationship between bearing capacity and share of socket,and the relationship between different rocks and share of base resistance,are discussed;the best socket lengths of different length piles are presented. |
