Study on One-dimensional Consolidation Test of Mucky Soil
In order to clarify the one-dimensional consolidation properties of mucky soil,this paper uses the research method of experimental soil mechanics to study the one-dimensional deformation and consolidation law of undisturbed mucky soil samples in a project.The results show that the time-strain curve in this project can be divided into three stages:mutation stage,transition stage and stable stage according to the change rate of strain,and it is found that the proportion of the main consolidation amount to the total consolidation amount increases with the increase of the depth of the undisturbed soil sample.At the same time,according to the e-p curve,it can be seen that the drainage condi-tions of the early sedimentary soil with deep burial are poor,and the consolidation speed is slow.Under the action of pressure,the drainage speed of the later sedimentary soil increases significantly.The research content of this paper further clarifies the one-dimensional consolidation law of muddy soil and has certain practical significance for improving the quality of engineering foundation treatment.
