Abstract
Soil shear strength is an important indicator of the mechanical properties of soil, which directly reflects the difficulty of shear deformation of soil under external force. At present, the detection of soil shear strength is mainly based on artificial field sampling and laboratory instrument analysis. However, these methods can not achieve long-term monitoring of the field. Therefore, there are some shortcomings such as complicated operation and large sampling error, which can not reflect the change of soil shear strength. In this paper, a shear strength measurement device based on shear wave velocity is proposed. If the shear wave velocity of soil can be measured in real time, the corresponding shear strength can be obtained and the on-site long-term monitoring can be achieved.
