摘　　要：结合最新研究成果,编制了筒型基础竖向极限承载力计算程序,可根据土壤参数和承载能力要求确定筒型基础的主要尺寸;同时使用ABAQUS和ANSYS软件建立筒型基础有限元模型,采用非线性接触方法模拟筒-土的边界,计算筒型基础的竖向极限承载力,两种软件的计算结果和编制程序的计算结果基本相同;最后对影响筒型基础竖向极限承载力的土壤参数进行了分析。Combining the newest research achievement,the bucket foundation vertical ultimate bearing capacity calculating program（＂Program＂ for short） can be used for the primary dimensions design of bucket foundation depending on the soil property and bearing capacity.The finite element model（FEM） is established with ANSYS and ABAQUS,the interface of the bucket and soil is simulated with non-linear contact method,the result of the vertical ultimate bearing capacity of bucket foundation with FEM and the Program are almost the same.At last,the soil property which affects the vertical bearing capacity of the bucket foundation is discussed.
