| Abstract: | A design method for DJM pile composite ground combined with both long and short piles is studied.The formula of bearing capacity for DJM pile composite ground,the additional stress acting on substrata,and the settlement of DJM pile composed ground are proposed in the paper.It is clear that the effective length of a pile has to be considered to calculate the bearing capacity.A practical project of deep soft ground treatment combined with both long and short DJM piles is presented.It is found that the proposed method is feasible. |
