| Abstract: | Ultimate strength of the large diameter pile with bulb shaped base is tested in a site of a practical engineering. The tests include a group of pure friction piles, a group of end bearing piles and two groups of piles with both friction and end bearing. Designing parameters of the longitudinal strength are determined. Also, the behaviors of the friction and end bearing pile are analysed. |
