For the settlement calculation of soft soil，the difference between stress consolidation degree and strain consolidation degree is neglected，and the soil stress history is not considered in the derivation of the corresponding conversion formula. We use the settlement calculation method considering e-lgp compression curve，consider the soil stress history，derive the conversion formula between stress consolidation degree and strain consolidation degree，analyze the difference between stress consolidation degree and strain consolidation degree，and the main influencing factors，and carry out the verification based on the reclamation project in Philippines，Pasay. The results show that consolidation degree is not equal to the strain consolidation degree，the difference between them is influenced by the compression characteristics of soil，natural gravity stress，stress history，and overlying additional load.
