摘　　要：通过对规范公式的推演,发现当基底反力不大于[p]([p]≥700k Pa,[p]与独立基础混凝土强度等级和尺寸有关)的情况下,验算基础受剪切承载力的规范公式8.2.9自然满足,不需验算;当基底反力比较大(p>[p])时,建议采用"全配筋式独立基础"或"短粗柱式基础"代替普通的独立基础。Base on deducing formulas in the code,it can see that,it is not need to check the shear bearing capability of spread foundation according to formula8. 2. 9,if the reaction under footing is not bigger than [p]（ [p] ≥700k Pa）. If the reaction under foundation is big enough（ p 〉[p]）,＂all side reinforced footing＂and＂short ＆ thick foundation＂are suggested.

关 键 词：扩展基础受剪切承载力 全配筋式独立基础 短粗柱式基础
