含水率是土的重要性质指标之一。本文分别采用微波法和标准烘箱法对细粒土和砂类土的含水率进行测试,分析土样质量、烘干时间等因素对微波法测试结果的影响;最后结合试验情况,对微波法含水率测试的注意事项进行总结。试验结果表明,微波法测含水率在工程施工质量控制中具有重要的实际意义,值得推广应用。 Moisture content is one of the important properties of the soil. In this paper, the microwave method and the standard oven method were used to test the moisture content of the fine grained soil and the sandy soil, and the influence of the quality of the soil sample and the drying time on the test results of the microwave method was analyzed. Finally, Rate test summary of the considerations. The test results show that the moisture content measured by microwave method has an important practical significance in engineering construction quality control and is worth popularizing and applying.
