堆载地基与邻近桩基的相互作用分析

On the interaction between adjacent pile and soil subjected to surcharge loads

本文在分析堆载条件下邻近桩基与土体的相互作用时 ,提出了改进弹性地基梁模型 ,采用最小势能原理推导了改进弹性地基梁的有限杆系法平衡方程 ,并编制了相应的分析程序EFBMPP 。

In order to analyses the pile soil interaction adjacent to superficial surcharge, the paper proposes the modified elastic foundation beam model, derives its stiff matrix of finite beam method and encodes the program EFBMPP. Then, some factors that affect the pile displacement and moment have been discussed.
