Research of the Shear Strength Test of the Soil on the Surface of Lop Nor Gobi

摘要

By applying the self-made field in-situ direct shear equipment, it makes a series of in-situ direct shear test researches on the soil （＜10cm）on the surface of the gravelly gobi in Lop Nor, Xinjiang, achieving its shear strength parameter. The conclusion that this paper gets not only provides the key parameters needed for the design of the gobi surface soil collection machine and the relevant assessment experiments, but also offers the reference for evaluating the similar soil shear strength of the gobi engineering construction.
