目前,国内对于黄土抗剪强度参数与含水量的相关研究还不够深入,本文针对晋南黄土进行固结排水三轴剪切试验,主要研究含水量对抗剪强度参数的影响规律。试验结果表明:围压较低时,随含水量的增大,黄土的强度降低更明显;抗剪强度参数c和φ随含水量的增大而减小,但均存在极小值,抗剪强度参数c比抗剪强度参数φ先达到极小值。 At present, the relative research on shear strength parameters and water content of loess in China is still not deep enough. In this paper, the triaxial shear tests of consolidated drainage of Jinnan loess are carried out. The influence of water content on the shear strength parameters is mainly studied. The results show that when the confining pressure is low, the strength of loess decreases more obviously with the increase of water content. The shear strength parameters c and φ decrease with the increase of water content, but both have minimum value, shear strength Strength parameter c than the shear strength parameter φ first reached a minimum value.
