Abstract

An investigation of an onshore wind turbine foundation was performed. The crack inspection on the top surface of footing and measurements were conducted to determine current damage state of the foundation. FE analysis was employed to predict the failure mode. The structural model including the piles and surrounding soil but excluding the tower was built. According to the static analysis with monotonic loading, the crack which had occurred from the tip of anchor plate, reached to the top surface of footing. This suggested that the failure mode of the foundation is possibly a corn-shape failure of the footing concrete.
