| 摘 要： | 基于三剪统一强度准则考虑中间主应力影响的特点,对太沙基地基极限承载力计算公式进行了修正。在修正式中,强度准则中的中间主应力效应参数b对地基极限承载力有影响。算例分析表明:当地基土的内摩擦角较大,b取其较大值时;当地基土的内摩擦角较小,b取其较小值时,修正式都能较好地反映地基极限承载力的真实情况。

| Abstract: | A modified formula of Terzaghi bearing capacities is proposed based on the triple shear unified failure criterion that can take the influence of the intermediate principal stress into consideration.In the formula,bearing capacities of the foundations are influenced by the effective parameter of the intermediate principal stress.The examples show that the modified formula can reveal the true facts when the inner frictional angles are relatively large and are equal to their large values,or when the inner fric... |
