| Abstract: | To correctly evaluate the deformation of soft clay and exactly calculate the settlement values and settlement process of soft clay mainly depend on the deformation indexes.The measured deformation indexes are affected by sampling depth,consolidation pressure,consolidation time and other factors.The research of consolidation and compression characteristics of marsh soft clay in different depths were carried out by using one-way consolidation test,multi-level load and increasing the time for each load stage.B... |
