摘　　要：针对中国、美国和欧盟的建筑地基基础设计规范,从设计原则、参数取值以及计算方法方面,对比分析了土体分类、地基承载力计算、扩展基础冲剪计算三大内容。研究结果表明:在土体分类方面,中、美、欧规范均分巨粒、粗粒和细粒,粒径划分上较为类似;在地基承载力计算方面,中标考虑对基础宽度和埋深的修正,欧标需进行内摩擦角的折减,美标需考虑安全系数的影响,算例结果表明中标较为保守;在扩展基础冲剪计算方面,按剪切和冲切条件控制计算基础厚度时,中标均较高,表明中标更为保守。From the aspects of design principle,parameter value and calculation method,this paper compares and analyzes the soil classification,the calculation of foundation bearing capacity and the calculation of extended foundation punching and shearing in Design Specification of Building Foundation among the PRC,the US and the EU.The results show that the classification of soils in the PRC,the US and the EU is divided into giant,coarse and fine grains,and the size division is similar.In the calculation of foundation bearing capacity,the PRC considers the correction of foundation width and buried depth,the EU needs to reduce the internal friction angle,and the US needs to consider the impact of safety factor.The results show that the PRC is more conservative,the EU is the second,and the US is the largest.In the calculation of extended foundation punching and shearing,when the foundation thickness is calculated according to the shearing conditions,the PRC is larger than the EU and the US.When the foundation thickness is calculated according to the punching conditions,the PRC is larger than the EU and less than the US.It suggests that the PRC is more conservative.
