| 摘 要： | 通过分析地基及基础的承载能力极限状态设计方法,指出:材料分项系数的取值与荷载分项系数的取值是互相匹配的,总安全系数法中的总安全系数综合了材料和荷载分项系数以及结构的重要性系数;按《建筑桩基技术规范》(JGJ94-94)、《建筑地基基础设计规范》(GB7-89)、TJ7-74和GB50007-2002进行地基土体在承载能力极限状态下的承载力设计计算,一般都能保证地基土体承载力的总安全系数不小于2.0;另外还指出,由小尺寸的浅层载荷板试验得到的地基承载力特征值需进行基础尺寸及埋深修正。

| Abstract: | The method of ground and foundation work′s design is analyzed,and is pointed out:the coefficient of material and load coordinated with each other,the general coefficient of safety has concluded the coefficient of material,load and importance of construction,and the general coefficients of safety in “The Code for Design of Pile Foundation”(JGJ 94-94),“Code for Design of Building Foundation”(TJ 7-74),(GB 7-89) and (GB 50007-2002),are all no less than 2.0,in addition,when the ground bearing capacity is confirmed by the small scale loading test of surface layer,the characteristic value of ground bearing capacity needs to be modified with foundation’s size and depth of embedment. |
