提出了一种简化、高效的多桩支承埋置基础的土-结构相互作用分析方法。在这里，一些相邻的桩被替换为一个单一的等效桩，以减少自由度的数量。将薄层单元法的计算结果加权平均为多点荷载解，计算土体的柔度。结合柔性体子结构技术可以考虑基础的埋置。将该方法与严格方法所得的阻抗函数和基础输入运动进行了比较，证明了该方法具有足够的精度和良好的效率。同时，还研究了相邻建筑物的影响，这些建筑物有埋置和桩基础支撑。
A simplified and efficient soil structure interaction method is presented for embedded foundation supported by a large number of piles. Here, some adjacent piles are replaced by a single equivalent pile in order to reduce the number of degrees of freedom. The multi-point load solutions, which are the weight average of the results derived from the thin layered element method, are introduced to compute the compliance of soil. The embedment of the foundation can be taken into consideration by combining the flexible volume substructure technique. The comparison of the impedance function and foundation input motion by the method with those by rigorous method is made and it is verified that the method is of sufficient accuracy and good efficiency. Also, the effects of adjacent buildings, which have embedment and supported by pile foundation, are studied.
