摘要
当前普遍采用的太沙基极限承载力公式中并未给出承载力系数Nγ的解析形式,而且Nc的表达方式在不同资料中不统一。针对以上情况,根据地基土的极限平衡原理,研究得出了条形基础底面完全粗糙条件下太沙基极限承载力系数Nγ′、Nc′的解析解。然后计算得出太沙基极限承载力系数的曲线以供查用。以上成果可为太沙基地基极限承载力公式的应用及研究工作提供参考。
In the K.Terzaghi ultimate bearing capacity formula,the coefficient Nγ has not been given in a definite expression and the factor of Nc is different in different material.To solve this problem,according to the ultimate balance theory,the analytical formula of Nγ and Nc are derived and the correctness of the factor Ng is proved for the strip foundation with absolute coarse base.At last,the curves of all the factor in K.Terzaghi ultimate bearing capacity are provided,which is valuable for the application and research of the K.Terzaghi ultimate bearing capacity theory.
