摘　　要：通过对单位桩体材料提供的承载力系数和桩的深度效应与群桩效应等问题的讨论与分析,简述了其对桩基设计合理与否的制约作用,介绍了在一定条件下,选择合理的桩径、长径比、桩间距的方法以及确定桩的平面布置和设计计算参数的方法,以尽可能地提高单位桩体材料提供的承载能力和群桩效率,达到优化设计的目的。The thesis discusses and analyzes pile material bearing coefficient, pile depth effect and pile group efficiency and other problems, briefly illustrates their constraints for rational pile foundation design, and introduces pile diameter, length diameter ratio and pile distance deter-mining methods and pile plane distribution determining methods and designing calculation parameter methods, with a view to improve the single pile material bearing capacity and pile group efficiency as much as possible and to achieve the goal of optimal design as well.

关 键 词：承载力系数 临界深度 端阻稳值 群桩效率
