摘要
根据成都地区某高层建筑深基坑护壁桩的实测资料，采用数值方法分析了护壁桩在基坑开挖过程中的变形规律．计算结果表明护壁桩具有柔性支护构件特征，由于圈梁对桩顶的有效约束使护壁桩的变形状态不同于悬臂构件．文中对桩顶圈梁的约束作用也进行了讨论．
Based on the measurements of the bending moments of two retaining piles in an excavation, a numerical method is applied to analyze the pile deformation and the binding forces of the top ring beam. It is shown that the retaining piles are flexible. The restraining forces on the top of the pile make the retaining piles work differently from the upright free-head shaft and should be taken into consideration in the design.
