TM-85型土壤密度计试验精度的研究
Study on Test Accuracy of TM-85 Soil Density Gauge
-
摘要: 在土工试验中,发现用TM-85型土壤密度计测定的粘粒含量比以往常用的移液管法测得的值偏高2-5%,本文对四支该种密度计逐支进行了刻度、沉降距离和弯液面等的校正研究,供同行参考。Abstract: In the soil test, it is found that T the content of clay particle taken from the TM-85 soil density gauge is 2-5% more than that obtained with the transfer pipet formerty used. Here four TM-85 gauges are studied one by one and corrected with regard to the reading, falling distances and curving surface, which may be a reference for colleagues.
