为了找到一种效率高、精度高的快速测定土的含水量的方法,分别用烘干法和微波法进行了红粘土含水量的对比试验。首先,通过对烘干法和不同组合(单个试样质量和微波炉加热火力的各种不同组合)下微波法试验结果的回归分析,得到了不同组合下微波法所得含水量与烘干法含水量的回归方程;其次,通过对不同组合下微波法试验结果的正交试验方差分析,确定了用微波法测定红粘土含水量的最优组合和最优回归方程;最后,对最优组合进行了试验验证。研究表明:采用微波法测定红粘土的含水量是可行的,且与烘干法相比,采用微波法测定红粘土含水量,可以大大提高工作效率,加快试验进程。
In order to find a method of rapid determination of soil moisture content with high efficiency and precision, comparative tests of water content of red clay by drying method and microwave method were carried out respectively. First of all, through the regression analysis of the drying method and different combinations (single sample quality and various combinations of microwave oven heating) under the microwave test results obtained under different combinations of moisture content obtained by the microwave method and drying method moisture content Secondly, the optimal combination and the optimal regression equation of the water content of red clay determined by microwave method were determined by orthogonal experimental variance analysis of the microwave test results under different combinations. At last, the optimal combination was determined Test verification. The results show that it is feasible to determine the water content of red clay by microwave method. Compared with the drying method, the determination of water content of red clay by microwave method can greatly improve the working efficiency and speed up the test process.
