摘要
阐述了桩基负摩擦力的产生与原理,总结了现有减少桩基负摩擦力的方法,提出了可以用锥形桩来减少欠固结软土地基中桩基的负摩阻力,并简要说明了锥形桩降低桩基负摩擦力的原理,最后建议用加密锥形群桩作为欠固结土地基基础来消除桩基负摩阻力。
The theoretical mechanism of the negative friction of pile is introduced firstly. Those methods of diminishing the negative friction of pile are summarized. The tapered pile is used to reduce the negative friction of pile and its mechanism is illustrated. Finally, a suggestion of using intensive tapered pile groups is put forward to diminish the negative friction of pile in under-consolidated soft subsoil.
