摘要

土体抗剪强度是表征土体力学特性的重要指标，它直接反映了土体在外力作用下剪切变形的难易程度。目前，土抗剪强度的检测主要是基于人工现场采样和实验室仪器分析。然而，这些方法无法实现对现场的长期监测。因此存在操作复杂、采样误差大等缺点，不能反映土体抗剪强度的变化。本文提出了一种基于剪切波速的剪切强度测量装置。如果能够实时测量土体的剪切波速，就可以得到相应的抗剪强度，实现现场的长期监测。

Development of device for measuring shear strength of soil wave based on piezoelectric effect

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.
