Abstract: Unlike a circular pile, the cross section of a rectangular barrette is nonaxisymmetrical. Therefore, not only the pile spacing but also the pile shape and the pile group layout will have influence on both the load-carrying behavior and the pile group effect of barrette groups. In order to analyze these influencing factors, a calculation method is proposed for obtaining the load-settlement relationship of the barrette groups with or without a rigid cap, using the Mindlin equation and the static force equilibrium equation. It has been found that, when designing a barrette group, barrettes should be aligned longitudinally (i.e., along their longer sides); and for attenuating the pile group effect of the barrettes of typical size, the face-to-face spacing among barrettes should be greater than 2 m.

Key words: barrette, pile group effect, three-dimensional analysis, high-rise pile cap, load-carrying behavior
