主 题：Wind turbine foundation Scour countermeasures Armouring countermeasures Flow-altering countermeasures MICP method
摘 要：Local scour at monopile foundations of offshore wind turbines is one of the most critical structural stability *** article reviews the contemporary methods of scour countermeasures at monopile *** methods include armouring countermeasures(e.g.,riprap protection)to enhance the anti-scour ability of the bed materials and flow-altering countermeasures(e.g.,collars and sacrificial piles)to reduce downflow or change flow patterns around the *** number and size-selection equations for riprap armour layers are summarised and ***,other alternative methods to riprap are briefly introduced and presented.A typical graph of the scour depth reduction with different collar sizes and elevations under specific test conditions is summarised and compared with a plot for a pile founded on a *** rates for different flow-altering countermeasures,including the collar,are listed and compared.A newly developed soil improvement method,namely microbially induced calcite precipitation(MICP),is also reviewed and introduced as a scour protection *** a popular bio-soil treatment method,MICP has a good potential as a scour countermeasure ***-soil treatment methods and traditional armouring methods are defined as active and passive soil enhancement scour countermeasures,respectively.
