摘要
本文利用三维弹塑性有限元法对水平荷载作用下群桩基础特性进行了分析,讨论了群桩基础水平荷载作用下的承载性状和破坏机理,并探讨了桩距、桩数、桩长、桩径和土质各种因素对群桩效应的影响,指出桩距和桩数是影响群桩效应的主要因素。
The pile group foundation under horizontal load is analyzed by using 3D elasticplastic finite element method in this paper, and the bearing character and destroy mechanism of pile group foundation under horizontal load are discussed. The influence of pile spacing, pile number, pile length, pile diameter and soil material factors on the pile group effect are also discussed, and the pile spacing and pile number which are the major factors to influence the pile group effect are put forward.
