粘土中水平受荷桩基计算方法

Calculation of Laterally Loaded Piles in Clay

摘要:

对于水平受荷桩的分析方法，目前多采用p-y曲线法，p-y曲线模型大都来源于实测。该方法概念清晰、密切结合现场试验，被认为是更加贴近实际的方法。通过对常用的实测p-y曲线模型的总结，可以看出实测p-y曲线形式复杂，普适性差，并且难以通过实测准确得到。而理想弹塑性模型形式简洁，通过选取合理参数，即可得到与实测相符合的结果。通过实例的对比分析，证明了理想弹塑性方法的p-y曲线有效性和适用性。因此，理想弹塑性方法可作为实测p-y曲线的替代方法应用于工程实践。

Abstract:

For analysis of laterally loaded piles in clay, the p-y curve method was widely used. Most p-y curve models were based on field tests, and were considered to be more realistic. Summary of commonly used experimented p-y curve models indicated that the form of measured p-y curves was complex and actual p-y curves were hardly founded out exactly. Elastic-plastic model was a simple model, which can predicted deformation behavior and load distribution of the lateral loaded piles in clay accurately by choosing appropriate parameters. After the calculation of the examples, the elastic-plastic method was proved to be simple, definite and universal, so it could be widely used instead the complex measured p-y curves in engineering.
