| 摘 要： | 利用ABAQUS有限元软件,建立4个PHC管桩有限元模型,分析桩型(AB型和A型)、箍筋间距和箍筋直径对PHC管桩受弯承载力的影响。比较了公式和有限元计算得出的极限弯矩之间的差异。分析结果表明,AB型管桩的受弯承载力大于A型管桩的受弯承载力,减小箍筋间距和增大箍筋直径不能提高PHC管桩的极限弯矩,有限元分析得到的结果大于公式计算的结果。

| Abstract: | Through the finite element software of ABAQUS,the impact of the pile type and stirrup on PHC pipe pile's flexural bearing capacity is analyzed.The difference of the ultimate bending moment between the formula and finite element is compared.The results show that: the flexural bearing capacity of AB-type is greater than that of A-type.Decreasing stirrup spacing and increasing stirrup diameter can't improve the ultimate bending moment of PHC pipe pile.The result of finite element is bigger than the result of the formula. |
