本文在不同形态水分划分试验的基础上,通过对不同形态水分与粘性土不同状态之间的相互关系的分析,形成了粘性土体中最大结合水含量就是塑限含水量这个新概念,从而提出了最大结合水含量塑限试验方法。该法物理意义明确,设备简单,操作方便,基本消除了人为误差,所得结果充分体现了粘性土的塑限特性,所以是目前比较完善的一种试验方法,建议推广采用。
Based on the analysis of different types of water division tests, this paper analyzes the relationship between different forms of water and different states of cohesive soil to form a new concept that the maximum combined water content in clay soil is the plastic limit water content. The maximum combined water content plastic limit test method. The method has clear physical meaning, simple equipment, convenient operation, and basically eliminates human error. The obtained result fully embodies the plastic limit characteristic of clay soil, so it is a relatively perfect test method at present, and it is recommended to be popularized and adopted.
