| Abstract: | It is difficult to use man made fill for foundation bearing stratum.CFS pile was adopted mainly for soft soil subgrade and for elimination of collapsibility of loess,but now its use can be extended to man made fill.Through field tests its effectiveness was tested.Bearing capacity of CSF pile composite subgrad,pile soil stress ratio,loading distribution and the improvement of soil between piles are analysed. |

| Keywords: | man made fill CFS pile composite subgrade pile soil stress ratio |
