Shear strength of Yellow River Estuary Soil Solidified by Using All-solid-waste Binder in Protecting Foundations of Offshore Wind Turbines.

A novel method for fluidized solidified soil protection, known as all-solid-waste binder fluidized solidified soil protection, is proposed to improve the anti-scour ability of soil in the foundations of offshore wind power turbines. The shear strength is used to evaluate the anti-scour ability of the fluidized solidified soil. Direct shear tests are conducted in the laboratory to study the effects of the vertical pressure, cement-water ratio, curing age, curing environment and mix proportions on the shear strength of the prepared fluidized solidified soil. Equations are derived for the anti-scour rate and shear strength, and the limiting anti-scour rate of the prepared fluidized solidified soil is determined. These results provide a theoretical basis for erosion protecting fluidized solidified soil in the foundations of offshore wind power turbines. [ABSTRACT FROM AUTHOR]
