Analysis and Prediction of Compaction Curve of High Plastic Limit Clay
This paper selected high plastic limit clay in Guangxi for indoor compaction test,analyzed the structural changes of soil sam-ples on both dry and wet sides of compaction curve,and used four-parameter equation to fit and predict.The results show that the shape of the compaction curve is closely related to the type of compaction work.The dry side of the curve presents a loose or dense flocculent structure,while the wet side is a dispersed structure.Through the limited test data near the optimal water content,a complete full com-paction curve can be derived.Given the parameters of the full compaction curve,only one compaction test point with 0% water content can accurately predict the complete full compaction curve of the soil sample under other compaction work.
