Abstract:
In 1943, Terzaghi gave the general solution of Terzaghi model when
the base is completely smooth and rough, but did not give the analytical solution
of the bearing capacity coefficient Nγ , nor the table value, only the curve.
Cheng Guoyong and Qiu Rui published the CQ complete analytical solution of
Terzaghi model in 2011, but the Nc and Nγ coefficients are abnormal, and the
formula has errors and omissions. In this paper, based on the previous studies,
the correct analytical solution of the ultimate bearing capacity coefficient of
Terzaghi model is obtained by using the principle of limit equilibrium.
Terzaghi 于1943 年给出了Terzaghi 模型对于基底完全光滑及基底完全粗糙时的通解,但未给出承载力系数Nγ 的解析解,也未给出数表值,仅给出了曲线图。程国勇、邱睿2011 年发表了Terzaghi 模型的CQ 完整解析解,但Nc、Nγ 系数数值异常,公式有错漏。本文在前人研究的基础上,用极限平衡原理重新推演,得到了Terzaghi 模型极限承载力系数的探正解析解。
