群桩效应群桩效应是指群桩中的每一根桩受地基相互作用的影响，使群桩的变形性状和承载力与单桩有所差异。群桩中单桩的变形性状或承载力特性与同一条件下单桩的比值，就称为群桩效率（ｅ）。作用于桩头的荷载往往是垂直方向或水平方向的，也可能是扭矩。各种荷载可以认为... Pile group effect Pile group effect refers to each pile in the group pile affected by the ground interaction, so that the group pile’s deformation properties and bearing capacity are different from the single pile. The deformation behavior or bearing capacity of a single pile in a pile group and the ratio of a single pile under the same conditions are called group pile efficiency (e). The load acting on the pile head is often vertical or horizontal and may also be torque. Various loads can be thought of...
