摘要：
A new scour countermeasure using fluidized solidified slurry for offshore monopile foundation has been proposed recently. Numerical analyses using a computational fluid dynamics（CFD）approach were conducted to simulate the pumping operation around the monopile in this paper. The effects of pumping location and material property of solidi-fied slurry on the residual rate of fluidized solidified slurry were investigated. The results show that for monopile，the choice of solidified slurry and pumping location is mainly related to the final retention rate of solidified fluid soil during the pumping operation. The fluidized solidified slurry with small flow value is contributed to increasing the retention rate. If the flow value is small，the location on the upstream of monopile and near the bottom of the scour pit is optimal. © 2024 Science Press. All rights reserved.
