近年来,随着对斜坡稳定性问题的深入研究,粘性土残余抗剪强度越来越受到人们的重视。尤其是已经产生了大滑动的滑坡,以及古老滑坡复活这样一类问题,其稳定与否往往受滑坡滑带土残余强度的控制。我国在室内测试滑坡滑带土残余强度研究方面,用三轴仪在试样预先切好的45°+φ/2 In recent years, along with the further research on slope stability problems, the residual shear strength of clay has been paid more and more attention by people. In particular, landslides with large slip and revival of ancient landslides have been generated, and their stability is often controlled by the residual strength of landslide slip-soil. In our country, the residual strength of landslide soil in the test of landslide was studied by using the triaxial apparatus to pre-cut 45 ° + φ / 2
