土的液限等效值求取方法研究

Method for obtaining the equivalent value of soil liquid limit

阐述不同标准规范下土的液塑限试验标准;用标准液塑限联合测定法测定土的17 mm液限、20 mm液限,生产成本高,而且效率低。通过液塑限联合法对工程实例的土样进行试验研究,结合天津地区的经验值总结出目前国内常见的10 mm液限、17 mm液限、20 mm液限值的求取方法,找到其相关性,并用公式表示出来。

In this paper, we introduced the standard of the liquid plastic limit test under different specifications. The 17 mmliquid limit, 20 mm liquid limit of the soil by standard combined determination of liquid plastic limit, which has high productioncost and low efficiency. Through the combined determination of liquid plastic limit, we tested the soil sample of the project.Combined with the experience value of Tianjin area, we summarized the common method for calculating the liquid limit of 10mm, 17 mm and 20 mm in China, found its correlation and expressed it with formula.
