摘　　要：分散性土具有遇水后易发生土体崩解分散的特点,针对黄河水这一特定水质,采用针孔鉴定试验,从分散性土的配土用水方面,对比了蒸馏水和黄河水两种不同水质情况下人工配制土样在终了水头、终了孔径、终了流量、水色及破坏形态等方面的区别。试验结果表明:黄河水作为配土用水的土样呈现出非分散性土特征,黄河水对土样的分散性具有明显抑制作用。Dispersion soil has the characteristics of disintegration and dispersion in water. In view of the Yellow River water, this particular water quality, using pinhole identification test, head end, aperture, flow, water color and damage form of artificial soil sample preparation using distilled water and the Yellow River water was compared. The results show that the soil sample preparation using the Yellow River water has no obvious char- acteristics of dispersion soil, that is the Yellow River water can inhibit the decentrality of soil sample dispersion.
