Study on Post-Construction Settlement of Soft Foundation Treatment Considering Secondary Consolidation
The calculation of the settlement after the soft foundation treatment is directly related to the unloading time of the soft foundation treatment. In order to study the post-construction settlement characteristics of soft foundation treatment under secondary consolidation, the numerical models of soft foundation without consideration of secondary consolidation and under secondary consolidation were established by MC (Mohr-Coulomb) constitutive and SSC(soft soil creep) constitutive construction, respectively, and the influencing factors of secondary consolidation were proposed γ and the existing settlement calculation formula was modified, and the results showed that: (1) The secondary consolidation has a significant effect on the sedimentation rate, and the sub-consolidation is only about 0.5 times of the non-secondary consolidation sedimentation rate, and it is recommended that the sub-consolidation impact factor should be 0.5–0.8. (2) The sedimentation rate calculated by the method proposed in this paper is similar to the measured data and has good applicability.
