摘要
本文利用有限元法计算考虑剪切变形时横向受力桩的内力和位移,并以此分析了剪切变形对桩顶位移和桩身最大弯矩的影响。分析认为:按现有铁路工程技术规范进行的横向受力桩基设计,剪切变形的影响极其微小,可以略去不计。
The internal forces and displacements of laterally-loaded pilefoundation are calculated,considering the influence of transverseshear defomation by means of finite element method.Based onthe calculated results,the effects of shear deformation ondisplacement at pile top and on maximum moment in pile bodyare analysed.It is concluded that the influence of shear defor-mation is so little that it can be neglected when designing a pilein accordance with existing standards.
