| 摘 要： | 桩侧土作用力是影响桩基稳定的重要因素,考虑桩-土之间的相互作用来研究桩基的屈曲问题则更加合理.在三维轴对称的情况下,借助于桩-土界面的连续条件和三角函数的正交性求得了土层对桩基的水平作用力,并在此基础上建立了桩基的弯曲方程,进而求得了桩基屈曲的特征方程,并研究了长径比和桩土模量比对临界轴向荷载的影响.

| Abstract: | The soil resistance of pile around is one of the important factors which affects the stability of the pile,thus taking into account the interaction of pile-soil is more reasonable to study the bucking of the pile.The horizontal force of soil to pile is obtained by the continuous conditions at the soil-pile and the orthogonality of trigonometric functions.Based on these results,the bending equation and characteristic equation of the pile are established under three dimensional axisymmetrical cases.The influe... |
