界限含水量试验方法的对比

Limit moisture content tests the method contrast

对碟式仪液限法、滚搓法塑限法和液、塑限联合测定法进行了对比分析,结果表明碟式仪液限法、滚搓法塑限法人为因素影响很大,所得成果的再现性和可比性较差,而液、塑限联合测定法易于掌握,采用电磁落锥可减少人为因素的影响,具有较好的成果再现性和精度。

Instrument on the disc test liquid limit,roll twist method test plastic limit and combined measurement method of liquid and plastic limits were compared,it showed that the influence of human factors is great,and the reproduction and comparability of results is poor from instrument on the disc test liquid limit,roll twist method test plastic limit,while the combined measurement method of liquid and plastic limits is easy to master,using the electromagnetic fall cone can be reduced influence of human factors,the results has good reproducibility and accuracy.
