目前国内外土的流限试验基本有碟式和圆锥式两种方法,其实质都是测定土在流限时的抗剪强度,然后间接地判定土的流限含水量。我国一般都采用圆锥法。该法又分为调试法和联合测定法,但均需经多次调配土的含水量才能完成,比较费工、费时。本文根据土的微观结构与流限关系特性,提出一种新的流限含水量确定方法—单点法,经大量资料分析对比,证明是可行的。
At present, there are basically two kinds of disk- and cone-type methods for measuring the flow limit of soils at home and abroad. The essence of these tests is to measure the shear strength of the soil at the flow limit, and then indirectly determine the flow limit water content of the soil. Cone method is generally used in our country. The law is divided into the debugging method and the joint determination method. However, the water content of the soil must be adjusted several times to complete the process. It is time-consuming and labor-intensive. In this paper, based on the relationship between the microstructure and the flow limit of soil, a new method for determination of the water content of the flow limit, the single point method, is proposed. After a large number of data analysis and comparison, it is proved to be feasible.
