传统的土壤强度测定方法均需直接接触土壤,该文提出一种利用微波反射效应测定土壤强度的遥测方法。采用一套简单的试验装置以测定土壤的微波反射损失并用之研究土壤的含水量、容重、土壤类型和贯入阻力对微波反射损失的影响。试验结果表明,在单对数坐标中土壤的微波反射损失随其圆锥指数增加而呈线性减少。
Traditional soil strength measurement methods need to be in direct contact with the soil. This paper presents a telemetry method that uses microwave reflection to measure soil strength. A simple test set-up was used to determine the microwave reflection loss of soil and to study the effect of soil moisture content, bulk density, soil type and penetration resistance on the microwave reflection loss. The experimental results show that the microwave reflection loss of soil in a single logarithmic scale decreases linearly with the increase of its cone index.
