土含水量的微波测定

The Determination of Water Content in the Soil using Microwave Method

微波含水量测定是近年来出现的一种新的快速测定含水量的方法。为进一步快速控制、分析岩土工程试验的影响因素,在实验室中经常需要含水量的快速测定,本文利用微波法和烘干法分别测定了黄土和砂土的含水量,分析了相对误差,并建立了微波法和烘干法之间的转换关系,为土工试验影响因素的快速分析定奠定了基础,同时该结果也可应用于工程现场的质量控制和质量检验。试验结果表明微波法在测定含水量时比烘干法更能节省时间、提高工作效率,是一种实用的测定含水量的方法。

Microwave method is a good method to test water content recently.To further rapidly control and analysis the impact of factors of the geotechnical engineering tests,in the lab we often need rapidly determination of water content.The paper tells the methods of microwave and drying and determines the loess and soil moisture content,analysising the relative error.The paper also establishs a relations of the conversion between microwave and drying which laid the foundation for the impact of soil tests for the rapid analysis of the factors.and the results can be applied to the construction site of quality control and quality inspection.The results showed that the microwave method of testing water content saves time more than drying,and improves work efficiency,and is a practical way of moisture.
