Abstract

With the development trend of deep-water offshore wind farms and large-scale wind turbines, the diameter of the fixed monopile foundation increases accordingly. The existing theoretical methods and simplified models cannot guide the engineer design accurately. It is urgent to evaluate the lateral bearing capacity of large diameter monopile under multi-layer foundation. According to the horizontal bearing capacity test data of five test piles in three wind fields, the parametric input of the finite element model is calibrated, and the engineering data of the horizontal test pile load to displacement curve is fitted. It is recommended that the elastic modulus of the finite element model should be 1 times of the compression modulus of the sand and 3 times of the clay.

Key words
