摘　　要：针对受到不同动荷载特性下的水平受力桩,利用PLAXIS有限元软件建立相应的数值模型,通过变动参数法分析了各个荷载条件下单桩基础的力学响应性状,进而对这些响应结果进行了深层次的机理分析。研究结果表明,随着荷载幅度的提高和循环次数的增大,桩基础的水平承载性能有所降低。而荷载频率的适当增高,有助于提高桩基础的水平承载性能。The response characteristics of the internal force of single pile under different load conditions was analyzed here by finite element numerical model which established by the finite element software PLAXIS. Then the mechanism of these response characteristics was carried out. The research results show that the single pile bearing performance reduced with the increase of load amplitude and cycle number. And appropriately increasing of the load frequency can help to improve the single pile bearing performance.
