Experimental Device and Study on Interfacial Shear Stress of the Laminar Soil

Abstract:

A designed measuring device of soil interfacial shear stress is introduced in this paper. We used the device for measuring the shear stress between the soil interface, of which the moisture content was 30% and the clay content were 5%, 9%, 15%, 21%, 30% respectively. The results show that the shear strength of experimental soil and friction between the layers decreases with the clay content increasing when the moisture content is 30% and clay content is more than 15%, and the results increase with the clay content increasing when the clay content is less than15%. Based on the study of the laminar soil interfacial shear stress, it provides the basis for the future research of the laminar motion of the sediment and the deposition of the liquefied motion soil.
