| 摘 要： | 地震作用下土-桩-结构相互作用(SSPSI)是桥梁抗震领域的一个重点和难点问题。在介绍动力p-y曲线分析模型的基础上,通过与试验对比验证其合理性,通过参数敏感性分析确定其影响参数,并对其进行了进一步探讨。研究发现:动力p-y曲线分析模型可较为全面地描述SSPSI,砂土摩擦角是该模型的主要参数,自由场土体应尽可能取较大的长度,地震动强度影响土体进入非线性的程度。

| Abstract: | Seismic soil-pile-structure interaction(SSPSI)is one of the most important and complex issue in the field of seismic resistance of bridges.Based on the introduction of dynamic p-y curve analysis model,whose rationality is verified with tests,sensitivity analysis on parameters and further discussion are done afterwards.It is found that SSPSI could be more comprehensive described by the dynamic p-y curve analysis model.Friction angle of sand is the main parameter of the model.Larger length of free field would... |
