摘要
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。
The soil behavior when exposed to microwave under controlled laboratory conditions was investigated. Tests were conducted with four types of artificial soils and one natural soil type.The effects of moisture content, soil type, density of soil and microwave frequency on microwave re-flection loss were examined. These variables were found to influence the microwave reflection loss. The results show a definite correlation between the microwave reflection loss and soil strength expressed in term of cone index.
