Abstract
The results of an investigation of the shear resistance for compacted dry and water-saturated sand are presented on the basis of the experimental-calculation analysis of the drag force at the quasi-stationary penetration stage of a cylindrical impactor. We used a method proposed earlier based on the inverse experiment technique and using a measuring rod with a flat end. It is shown that with almost the complete water saturation of sand its shear properties decrease but remain significant in the practically important range of penetration rates.
