实例分析表明，由于桩侧负摩阻力的影响，单桩承载力大为降低。产生负摩阻力的土层，不宜采用端承型桩基。
The greatly reduced capacity of a single pile resulting from the negative friction leaves the end-bearing pile unsuitable in the backfilling soil.
通过分析计算，指出了支盘的承力特性具有明显的时间效应和端承性质，揭示了支盘桩高承载力和S型Q-S曲线的内涵。
The obvious time effect and end-bearing behavior of bearing disks are pointed out by means of analyses. The high bearing capacity and S-shaped Q-S curve of squeezed branch piles are highlighted.
