| Abstract: | By indoor multi -stage loading one -dimensional consolidation creep test of marine soft soil , under different stress levels ,this paper analyzes the soft soil deformation development law over time , the change rule of secondary consolidation coefficient and the secondary consolidation deformation relationship with different loading history . Relevant test results provide experiment basis for correctly forecasting the change rule of soft soil foundation settlement over time , andfor the rationalization model with reducing post construction creep settlement calculation . |

| Keywords: | marine soft soil secondary consolidation secondary consolidation coefficient post construction settlement |
