| 摘 要： | 在远场地震作用下单桩横向地震响应研究的基础上，引入相互作用因子，研究了远场地震作用下成层地基中桩与桩的横向动力相互作用，得到了桩间距、桩土刚度比、桩顶约束条件、瑞利波入射角度、震动频率是影响群桩横向动力相互作用主要因素的结论，为进一步研究远场地震作用下群桩的横向地震响应打下了基础。

| Abstract: | Based on the research on lateral seismic response of single pile induced by far-field earthquake, the lateral dynamic interaction between pile and pile was studied by introducing the dynamic interaction factor. From this, it is concluded that the pile spacing, pile-soil stiffness ratio, pile-head constraining condition, incident angle of Rayleigh waves, and seismic wave frequency are the main effects on the lateral dynamic interaction between piles. The conclusions of this paper lay the foundation for the further resarch of group pile during far-field earthquakes. |
