本文从结构整体性观点出发，以上部结构为主导并引入带多桩台的壁式框架模型，对拉身－土体系综合引用桩顶阻抗理论和方法来考虑群桩动效应，提出可考虑多个桩台的不同摇摆效应的桩基高层结构完整体系的水平地震响应整体分析方法，同时分析了典型的高层框－剪结构的动力特点。引用动态群桩基础试验模型验证，结果良好，并用可比较的数字例说明，所提出的分析方法比假设刚性地基或单一刚性桩台精确，仅增加有限未知量，对实际工程切实可行。
From the point of view of structural integrity, the above structure is dominated by the introduction of a wall frame model with multiple piles. The theory and method of the pile-top soil resistance are taken into consideration to consider the dynamic effect of the piles and can be considered more. The horizontal seismic response of a complete system of pile foundation high-rise structures with different rocking effect of pile post is analyzed. At the same time, the dynamic characteristics of a typical high-rise frame-shear structure are analyzed. The dynamic pile group foundation test model is verified and the result is good. Using comparable figures, the proposed analysis method is more accurate than the assumption of a rigid foundation or a single rigid pile, and only the limited unknown quantity is increased, which is practical and feasible for practical engineering.
