- Abstract
The liquid limit and plastic limit is an important parameter which can classify the fine grain soil and evaluate the property of projects. The liquid-plastic limit test and particle analysis test of soft clay near the seaport of Bohai Sea had been carried out to study the influencing factors of the liquid-plastic limit of the fine clay in this area and some suggestions were put forward. The research results show that the plasticity of soil can be affected by colloidal particles content of soil. There are certain limits and ranges when reflecting the plasticity of soil samples. For the soil samples studied, the critical value of colloidal particles content is 7.5%. The experimental study on the depth range of the measure point in different standards found it is different. The reason for the deviation may be that the falling depth of measure point and the corresponding water content are ideal nonlinear. It is suggested that this factor should be considered in the joint determination of liquid and plastic limit, so that the result is closer to the true value.
