本文对常用的刚结模型、铰结模型、接触模型、简化模型和弹簧模型五种桩-土动力相互作用分析模型进行了对比研究,分析发现:不同的分析模型有不同的适用范围,在桩-土动力相互作用分析时应根据所关心的问题选用不同的分析模型。本文给出了选择模型的建议,一般优先采用接触模型,次优为铰结模型。
Five different analytical models of pile-soil dynamic interaction, including rigid nodes model, flexible nodes model, touch model, simplified model and spring model, are studied. The different models are fitted for different conditions. When we study the pile-soil dynamic interaction, the touch model is the best one, then is the flexible nodes model.
