Limit lateral resistance of XCC pile group in undrained soil

Zhou, Hang / Liu, Hanlong / Li, Yingzhen / Ding, Xuanming

Abstract This paper investigates the issue of laterally loaded X-section cast-in-place concrete (XCC) pile group in undrained soil and, in particular, evaluates limit lateral resistance (LLR) through finite element limit analysis. Four types of XCC pile groups that are commonly used in practice are selected for discussion here. Both the upper- and lower-bound numerical results for the LLR of the XCC pile groups are presented. The influence of loading direction, pile group shape, and XCC pile cross-sectional shape is evaluated with a series of parametric studies. Design equations are subsequently proposed for computing the LLR of four types of XCC pile groups in undrained soil.
