AN SIMPLIFIED METHOD FOR SETTLEMENT OF RIGID-PILE COMPOSITE FOUNDATION

Chi Yuejun Song Erxiang Chen Zhaoyuan (Tsinghua University)  
A method for settlement of composite foundation with rigid-pile is proposed in the paper. It is named two-layer stress method. It is based on the experimental results and theoretical study of the current code. It is found that the stress distribution at the top of the soil among the piles and the substratum are governed by the dimensionless regressive formula. The settlements then can be evaluated by the layer-wise summation method. The results of the proposed method are compared with that of the field measured. It is shown that the comparison is in good agreement. The method is now applied to 24 cases of engineering project.
