循环水平荷载作用下的群桩性状分析

Research on the Behavior of Pile Groups under Cyclic Lateral Loads

在实际工程中,很多桩基础的破坏是风、波浪或者地震等循环水平荷载的作用所致,且这些桩基础往往布置成群桩的形式。结合前人的试验模型和理论研究成果,探讨了循环水平荷载作用下桩—土之间的相互作用、循环水平荷载对桩身刚度的影响,以及桩与桩之间的相互作用效应,循环水平荷载对群桩荷载分配及群桩基础轴向承载力的影响。

This paper presents a summary of a literature review on models and theories on soil-pile interaction under cyclie lateral loads and how loads influence on the stiffness of pile group. Furthermore. the interaction effect in pile groups such as load distribution among the piles, group efficiency and its effect on pile axial capacity are discussed.
