探讨了GB 50007—2011建筑地基基础设计规范中基础底板弯矩计算公式的由来,介绍了欧美规范在计算底板弯矩时与中国规范的不同之处,基于欧美规范的计算规则,推导了当偏心距大于1/6基础宽度时基础底板弯矩的计算方法。最后,提出了几点计算基础底板弯矩需要注意的问题。 This paper discusses the origin of calculation formula of base plate bending moment in GB 50007-2011 basic design code of building foundation, introduces the differences between Chinese and European norms when calculating base plate bending moment, and based on the calculation rules of European and American norms, Calculation method of base plate bending moment when it is more than 1/6 base width. Finally, some problems that need to be paid attention to when calculating the bending moment of foundation slab are put forward.
