摘要:
对水平载荷作用下斜桩的承载变形性状进行了数值模拟，分析了桩身倾角、桩顶约束条件及竖向载荷等因素对斜桩水平承载力的影响．数值分析结果表明：桩身倾角对斜桩水平承载力有较大影响，正斜桩的水平承载力大于直桩的水平承载力，而负斜桩的水平承载力小于直桩的水平承载力．桩顶竖向上拔荷载会提高正斜桩的水平承载力，但会降低负斜桩的水平承载力；桩顶竖向下压荷载会降低正斜桩的水平承载力，但会提高负斜桩的水平承载力．与桩顶自由时相比，桩顶设置承台会使斜桩桩顶水平位移明显减小．
Abstract:
Behavior of single batter piles under horizontal load was modeled by means of FEM, the influence of shaft inclined angle, pile head constrains as well as vertical load applied on the pile head on the behavior of batter piles was analyzed. It was showed that the bearing capacity of batter piles is notably affected by the shaft inclined angle. The horizontal bearing capacity of vertical piles is less than that of the positive batter piles but greater than that of the negative batter piles. The existence of uplift load on pile head will improve the horizontal bearing capacity of positive batter piles while decrease the negative batter pile bearing capacity. On the contrary, the compression loads applied on pile head will decrease the horizontal bearing capacity of positive batter piles while increase that of the negative batter piles. Compared to the batter piles without cap, horizontal displacement could be efficiently reduced with the introduction of pile-cap embedded in soil
