The shear strength of soil refers to the ultimate resistance of the shear stress generated by the external load of the soil. The strength problem is one of the most important basic contents of soil mechanics, and shear failure is an important feature of strength damage. At present, the monitoring methods of the soil shear strength device, such as indoor direct shear test, triaxle compression test, large-scale direct shear test on site, and on-site cross shear test, cannot realize real-time measurement in situ in the long-term field. In this paper, a device for measuring the shear strength of soil based on shear wave velocity is proposed, and the shear strength of the soil in situ can be obtained in real time.
