Controlling and multi-stage loading of gravity revetment structure on soft foundation

According to the monitoring data analysis of the transformation and relocation project in the eastern region of Dalian port,the control effect of multi-stage loading of gravity revetment structure on soft foundation was expounded.Based on the theoretical calculation and data analysis,the construction load was compared with the critical edge pressure and the load when the critical plastic depth developed to 1/4 base width.Then the reason of subgrade deformation was found out.After adjusting the load magnitude and the alarm value,the further deformation and shear failure of the foundation were prevented.The correlative engineering experience is accumulated and provided as reference for analogous projects.
