摘　　要：采用有限元数值方法对一个场地建筑群的单桩载荷试验进行了有限元数值模拟,从数值分析理论和参数取值等方面进行了论述,数值模拟分析了桩侧阻端阻的分布情况、桩基极限承载力等岩土工程应用问题,通过与14栋建筑物的单桩原位载荷试验对比分析认为,采用的单桩载荷试验有限元数值模拟方法,理论依据充分,参数选取便利,具有一定的应用前景。The finite element numerical method is used to simulate the single pile loading test of a site complex. The theoretical basis of numerical analysis and parameter selection are systematically described. The distribution of pile side friction and end resistance, ultimate bearing capacity of pile foundation and other geotechnical engineering applications are analyzed by numerical simulation. Compared with the in-situ loading test of 13 buildings, the finite element numerical simulation method of single pile loading test adopted in this paper has sufficient theoretical basis, convenient parameter selection, it has a certain application prospect.
