Abstract

Based on the foundation design of an onshore wind power project in China, the finite element analysis by Midas GTS NX is used to study the stress distribution and the overall displacement of the wind turbine foundation anchored by prestressed rock bolt. This work focuses on the position of the most unfavorable stress of foundation under load condition, and the influence of different bolt diameters on the overall displacement of foundation. The results show that the stress at the junction of foundation and platform column, and the anchor end of rock bolt are significantly larger than other positions, which should be paid attention to in design. The foundation displacement decreases with the increase of bolt diameter, but when the bolt diameter is greater than 60mm, the change trend decreases. Safe and economical bolt diameter should be selected in the design.
