[提要] 基于有限元分析理论编制了三维块体有限元分析程序FEP3D。应用该程序可实现高层建筑中厚板结构的内力分析。工程实例分析表明：FEP3D的计算结果与商业通用软件ALGOR FEAS的计算结果一致性较好，而使用FEP3D进行计算只需划分较稀疏的网格即可达到较好的精度，且该程序可将应力值合成内力值，为工程设计提供直接的应用。

The finite element analysis program of 3 dimensional solid element FEP3D is developed on the basis of the finite element analysis theory. This program can be used to analyze the internal force in the thick plate of highrise building foundation. The analysis results of the engineering example obtained from FEP3D agree well with those from the common commercial software ALGOR FEAS. Furthermore, the results of high precision can be gained with less amount of mesh in FEP3D, and this program can complete the function of integrating stress into internal force which leads to the direct application in the engineering design.
