摘要
通过对单位桩体材料提供的承载力系数以及桩的深度效应和群桩效应问题的讨论与分析,简述了它们对桩基几何设计合理与否的制约作用,提出在一定技术条件下,如何选择合理的桩径、长径比、桩间距和如何确定桩的平面布置问题,以尽可能地提高单位桩体材料的承载能力和群桩效率。
It discusses the effect which determine rationality of geometric design for pile foundation by analyzing coefficient of bearing capacity in unity pile .depth effect of pile and group effect of piles, points out how to chcose pile diameter.stenderness ratio .spacing of pile and borizontal layout of pile under definite condition to improve bearing capacity of unity pile mad ratio of piles.
