Abstract:Compared with the traditional gravity foundation,pile foundation,bucket foundation has simple structure,low cost,convenient transpor-tation,can be reused,and the bad in soft clay ground has irreplaceable advantages. Based on the finite element analysis and limit equilibrium anal-ysis of a new type of horizontal limit bearing force of bucket foundation,the results were compared. The results show that:through the finite element analysis,the model of bucket foundation is given priority to with rotational failure,when in the state of limit equilibrium,the barrel body side and soil separation occurs;and with the increase of undrained shear strength of clay increases the ultimate bearing capacity of bucket foundation;based on the finite element analysis,the limit equilibrium analysis method of theoretical formula calculation of bearing capacity of the bucket foundation level limit,and with the finite element analysis results,verify the applicability of the formula.
