Abstract:Equations between compression modulus,ostmotic coefficient,consolidation coefficient,seepage distance and effective consolidation stress are derived based on present results of research and considering characteristics of consolidation and settlement of shallow improvement of slurry stratum.Then change of consolidation and settlement parameters due to effective consolidation stress can be taken into account.The effect of soil column to consolidation is taken into account referring to the smear effect.The influence of bending drainage on consolidation is also analyzed.It is shown that the consolidation coefficient increases along with effective consolidation stress,the soil column is beneficial to consolidation,and the strain degree of consolidation is bigger than the stress degree of consolidation.The influence of bending drainage and decrease of thickness on consolidation can be neglected.
