摘　　要：通过室内模型实验,研究有无联系梁、联系梁厚度以及排间距对抗滑桩抗滑性能的影响。双排桩组合有联系梁时的抗滑承载力超出无联系梁的40%;联系梁强度能满足变形要求时,其厚度或刚度的增加对加强抗滑性能的作用不大;排间距较小的支护结构侧向承载力较大。The indoor model experiment was conducted to study how the connect beam, the beam thickness and the row space influence the anti-sliding performance of the piles. The load capacity of double-row piles with beams exceeds that of double-row piles without them by 40%. Thicker or stiffer beams won＇t enhance their anti-sliding performance much than, they meet the deformation requirements. The supporting structure with smaller row space has larger capacity of lateral load.
