| Abstract: | The pile driving effects of driven cast*.in*.place tubular piles are analytically analyzed by making use of cylindrical cavity expansion theory,and by comparison with general piles,its superiorities in respect of disturbing soils are displayed. Because both its inner and external surface can bear friction,and it is hollow,so its bearing capacity is higher and pile driving effect is smaller than any kind else,and is worth being popularized. |
