摘要
在《工程岩土学》中规定粘土的液限可采用天然含水状态的土样或风干土样测定。这在理论上是可行的,实践证明绝大多数土也是适宜的,但贵州红粘土用天然含水状态的土样或风干土样测定液限值却常常存在差异。通过实验资料,分析产生差异的原因,认为造成这种差异的主要原因是由红粘土的"干燥不可逆"效应所引起的。
In the present geotechnical test specification,the determined liquid limit of clay can be assessed by sample in the state of natural or dried.This is practicable in the theory,and also is proved by tests to be suitable to most cases.But there is difference between liquid limit assessment of red clay sample in the state of natural or drying in Guizhou.Based on the test data,this paper analyzes the reasons for the difference and comes to a conclusion that it is caused by effect of drying irreversible of red clay.
