| 摘 要： | 通过将P-Y曲线与有限元法相结合，探讨了多层地基中水平承栽桩非线性受力特性分析的简捷、精确方法．该方法假定桩间土对桩单元的水平抗力按线性分布，引入线性插值函数模拟单元约束反力，导出了桩一土相互作用的P-Y曲线非线性有限元计算模型，利用直接迭代算法进行编程求解．工程实例分析表明：计算结果与m法相比具有良好的一致性，该方法简便，稳定性好，便于工程设计应用。

| Abstract: | By combining P-Y curves with pole system FEM, a method of simulating the pile-soil interaction more accurate and more suitable to multiplayer soil is discussed. Assuming pile element subjected to linear load respectively and using linear interpolation function to approximate the soil's anti force to piles, a new pile-soil interaction element calculated model is designed. Then compiling procedure with direct iterative method. The result of example consist with m method perfectly. This method has proved available for its simpleness and stability in practical project. |
