在粘性土颗粒分析试验中,对颗粒分散的方法一直存在着两种不同的方案。一种是“机械(物理)分散”;另一种是“化学分散”。国际上绝大多数试验室采用机械分散的方法,即悬液振晃法。其目的是研究土作为一种材料,它在工程中所遇到的营力和工作环境条件主要是机械(物理)作用。因此需要用机械的方法分散其颗粒,而不宜采用化学方法去追求高度的分散。但是我国的多数单位至今仍沿用化学分散法。这种方法是基于与上不同的考虑,是从土的微观结构来研究的。而我们需要的倒是土的最基本的 In cohesive soil particle analysis tests, there have been two different approaches to particle dispersion. One is “mechanical (physical) dispersion” and the other is “chemical dispersion.” The vast majority of laboratories in the world adopt the mechanical dispersion method, namely the suspension vibrating method. Its purpose is to study soil as a kind of material, and its operating forces and working environment conditions encountered in engineering are mainly mechanical (physical) effects. Therefore, it is necessary to use mechanical methods to disperse its particles, and it is not appropriate to use chemical methods to pursue a high degree of dispersion. However, most units in our country still use the chemical dispersion method. This method is based on different considerations and is studied from the microstructure of the soil. And what we need is the most basic of soil.
