Abstract This paper investigates the time-dependent response of laterally loaded single piles and pile groups embedded in transversely isotropic saturated viscoelastic soils. The solution for single piles subjected to lateral loads is solved by the coupling of the boundary element method and the Timoshenko beam theory. In the analysis of the pile group, the interaction between piles is taken into account and the generalized displacements caused by all piles are obtained by superimposing the influences of boundary forces on the soil-pile interfaces. The load distribution from the pile cap to pile tops is involved in the analysis. The presented method of laterally loaded piles and pile groups is verified through several examples, and the influences of some key parameters including transverse isotropy, the viscoelastic parameters, the flexibility coefficient, the slenderness ratio and the pile spacing are investigated by numerical examples.

横向各向同性饱和粘弹性土中侧向荷载桩和桩群的瞬态响应

摘要 本文研究了横向各向同性饱和粘弹性土中单桩和桩群横向受力的瞬态响应。通过边界元法和铁木辛哥梁理论的耦合求解单桩承受侧向荷载的解。在桩群分析中，考虑了桩间相互作用，通过叠加边界力对土桩界面的影响，得到所有桩引起的广义位移。分析中涉及从桩帽到桩顶的载荷分布。通过几个算例验证了所提出的侧向荷载桩群计算方法，以及横向各向同性、粘弹性参数、
