[提要]  通过对新近实施的《建筑地基基础设计规范》( GB50007-2002)的学习，作者体会到过去许多争论不一的问题在新规范中均有了明确的结论，如大直径桩的桩端尺寸效应、单桩竖向承载力分项系数等问题。文中对这些问题进行了讨论，供参考。
[关键词]  尺寸效应系数  分项系数  护坡桩  地基承载力  特征值

Code for design of building foundation ( GB50007-2002)is executed in Apr11, 2002. Some confused questions are answered clearly in the new code. For example, dimensional effect of big-diameter pile, separate coefficient of single pile, and so on. They are discussed for referrence.
Keywords: dimensional effect; separate coefficient; slope-guard pile; characteristic value; sub-grade bearing capacity
