摘要
桩侧土体的弹性抗力假定为两部分组成,通过选择合适的桩柱挠曲变形函数,用瑞利—里兹法求解其临界荷载,分析桩周土抗力模式对超长桩的临界荷载及计算长度的影响关系。
The soil resistance on the side of pile is assumed to comprise two parts. By choosing suitable wrapping function of pile, the critical load is solved by Rayleigh- Ritz method, and then the relations between resistance model and the critical load and calculated length of pile are analyzed.
