Influence of load on secondary consolidation deformation of soft soils

The conventional method of computing the secondary consolidation of soft soils does not reflect the influence of load.However,it is shown that the secondary compression is obviously influenced by load.The relationship between the secondary consolidation deformation and load were discussed and the characteristics of the secondary consolidation of normally consolidated soils were emphansized in discussion,and some rules were concluded and analyzed.The results were as follows: for the over-consolidated soils,coefficient of the secondary consolidation increased with load;for normal-consolidated soils,it decreased with load.Based on the results,the computation method for deformation of the secondary consolidation reflecting the influence of consolidation pressure was developed.
