土体电阻率变化特性主要决定于含水量的变化,文章通过电阻率法测定土体不同深度连续时段的视电阻率,统计得到含水量变化深度的范围。试验表明这种方法简便有效,且对土体不产生扰动。
The change of soil electrical resistivity mainly depends on the change of water content. The resistivity method is used to determine the apparent resistivity of soil at different depths for successive periods. The range of water depth variation is obtained. Experiments show that this method is simple and effective, and does not disturb the soil.
