Failure Analysis and Countermeasure Study on Prestressed Anchor Bolt of Wind Turbine Generator System
In recent years,a large number of wind turbine generator systems have been put into operation,and the collapsing accidents of wind turbine have occurred frequently in various regions,some of which are caused by the failure of prestressed anchor bolts.After analysis of the failure cases of anchor bolts,such as foundation defects,improper use of tools,and improper installation of anchor cage,the corresponding solutions and preventive measures,such as drilling holes in the location of foundation defects,using inorganic and organic grouting materials to reinforce the foundation,have been obtained,and good results have been achieved,which has further promotion value.
