摘要
利用有限元分析软件ABAQUS对不同桩靴攻角情况下海床土体的变形规律进行详细分析,给出桩靴周围土体的变形规律和桩靴极限承载能力。基于上述结果,揭示在攻角变化情况下桩靴周围土体的失稳机理,并给出较为实用的承载力计算公式。
Using the finite element analysis software ABAQUS,the deformation rule of the seabed soil under different attack angles is analyzed in detail,and the deformation rule of the soil around the pile shoe and the ultimate bearing capacity of the pile shoe are given.Based on the above results,the instability mechanism of the soil around the pile shoe under the change of the attack angle is revealed,and a more practical calculation formula of bearing capacity is given.
