Study on secondary resilience deformation of soft soil under unloading

CHANG Qing,YU Xiang-juan,DONG Wei-jun(Geotechnical Research Institute of Hohai University,Nanjing 210098,China)  
Creep experiment was performed on silt samples from the right section BK0+250 of Shantou-Jieyang Expressway.The method for classification of the primary and secondary resilience deformation of undisturbed soil and disturbed soil was determined by analysis of the experimental result.It is concluded that the coefficients of secondary resilience of the two soil samples are the same under the condition that the resilience ratios of the soil samples are the same,while the maximum pre-loads are different;otherwise,if the resilience ratios are different,the coefficients of secondary resilience of the two soil samples increase with the increase of the resilience ratios under the same maximum pre-loads.
