| Abstract: | A new idea of setting several step flanges or multi-section expansive butts along the pile shaft is presented for non-rock-inlaid manual piles. By this method,the vertical load-bearing capacity of single pile can be increased,and remarkable economic-technical effect can be achieved. This method can be used for design reference. |

| Keywords: | mannal pile load-bearing capacity multi-section expansive butt |
