【 摘 要 】

Centrifuge model test and finite element simulation were used to study the stability of solidified soil embankment in offshore mold bags. Through centrifugal model test, the settlement, pore water pressure variation and consolidation deformation of the foundation in the filling and filling stage of the mold bag solidified soil embankment are analyzed and compared with the actual engineering monitoring results. The test results show that the centrifugal model test and finite element simulation results are similar under normal construction conditions, the foundation deformation is mainly settlement, the pore water pressure basically dissipates within six months after the completion of embankment filling, and the foundation failure mode is caused by insufficient bearing capacity. The model test results are consistent with the actual engineering monitoring results.
