| 摘 要： | 本文提出了一种新桩型—带翼板预应力管桩。该种桩型适用于具有深厚软土的地层条件,它的特点是桩端带有一个扩大头,桩侧按一定间隔设置翼板并在翼板间灌砂,分别用于提高桩端阻力及桩侧阻力。本文对该种桩型的施工工艺、设计方法进行了叙述,并进行了静载荷对比试验研究。初步分析研究结果表明,该种桩型能显著提高单桩承载力。

| Abstract: | In this paper,a new type of prestressed concrete pipe pile with wing plates is presented. This type of pile is suitable for the geological conditions with targe depth soft solts.Its features include: an enlarged base at pile bottom,wing plates in equi valent interrals and sand fill arrownd pile shaft for improving tip r esistance and side friction.Construction process and design method are pr esented, and the bearing capacity of this pile type is studied preliminarily bed comparin g with test date. |
