| 摘 要： | 桩与地基土之间的相互作用是横向承载桩研究的重要组成部分，相互作用的土反力是挠度和深度的非线性函数，即桩的变形和受力之间呈非线性变化，这种非线性导致了横向承载桩的分析计算十分繁杂。针对问题研究的复杂性，从考虑位移的朗肯土压力理论入手，根据桩出现挠度后引起周边土体的位移量，推导出桩周土反力表达式，在不引入任何地基模型的条件下计算桩身任意深度处基于桩体位移的土反力，简化了问题的分析过程。通过设定算例进行分析，所得出的结果与p-y曲线结果以及实际情况一致，证明了该计算方法的合理性。

| Abstract: | Pile-soil interaction plays important role in lateral loaded pile research. Soil pressure caused by interaction is the nonlinear function of displacement and depth. That is the displacement and stress of pile behaves nonlinear relationship, which results in complexity of analysis and calculation. In allusion to the complexity of the lateral loaded pile, it begins with Rankine’s earth pressure theory considering displacement. This paper deduces the calculation formula of soil pressure around the pile according to the displacement caused by deflection of pile. The formula can be used to calculate soil pressure based on displacement at any point without regard to foundation model. Compared to other analysis theory, this approach is simpler. In order to verify the rationality of the formula, authors take an example to set forth the process of analysis and calculation. The results are in accordance with the results of that p-y curve theory and practice. |
