ANALYSIS OF PILE UNDER LATERAL LOAD CONSIDERING EMBEDDED DEFORMATION

Based on elastic theory and assumption that there is embedded deformation between pile and soil,the deformation and load of pile under lateral load are analyzed.The parameters of pile under lateral load are studied as compared with“m”method.The analysis of the case indicates that the result from the model agrees well with the actual measurement.Considering the pile-soil and pile-pile interactions of the model,it is favorable to analyze group piles.The pile with bigger diameter can bear larger lateral load.Along with the pile′s diameter increasing to specified value,the lateral bearing capacity of pile can′t be improved obviously.The longer pile can′t bear more lateral load.And there is a critical pile length.The improved critical side resistance can reduce the lateral displacement of pile head,and can improve the lateral bearing capacity of the pile.The “m ” method assumes the side resistance in the ground is zero,which does not agree with that in clay foundation.
