以黄土坡滑坡滑带土为研究对象,利用环剪仪研究了滑带土天然样和饱和样在不同法向应力条件下的峰值强度与残余强度特性,并对残余强度的剪切位移进行了初步探讨。结果表明:有效法向应力越大,滑带土颗粒越容易沿剪切方向完成定向排列;同级有效法向应力下,饱和样达到残余强度所需的最小剪切位移比天然样的大,但是其定向排列的程度要大。
Taking the landslide landslide in Huangtupo landslide as the research object, the peak strength and residual strength characteristics of natural and saturated samples of landslide soil under different normal stress conditions were studied by means of ring shear, and the shear displacement of residual strength Preliminary discussion. The results show that the larger the effective normal stress is, the easier the slip-soil particles are to be aligned along the shear direction. The minimum shear displacement required to reach the residual strength under the same normal effective stress is larger than that of the natural sample. However, the degree of orientation should be large.
