| Abstract: |
| The factor values of pile group effect of pile end resistance in sandy compound pile foundation, calculated by using a 3 dimension elastic plastic finite element method, are lower than those in the "Technical Code for Building Pile Foundations". |
| Key words: compound pile foundation,end resistance of pile,efficiency factor of pile group,finite element method, |
