Design and Analysis of Foundations for Onshore Tall Wind Turbines
Wind turbines play vital role in producing sustainable and clean energy to fulfill the growing need of energy. However, the design of foundation to support wind turbines, especially the taller tower which access steady and higher speed wind is always a challenge due to larger loads exerted at the foundation level. In this paper, the economic advantage of using raft foundation, pile group foundation, and piled-raft foundation is discussed based on the preliminary design results and parametric studies. For the sample design, the axial load, lateral load, and moment at the base of the tower were computed assuming the tower height of 130 m and mean wind speed of 160 mph. The comparison of the volume of material required for each foundation type showed that the piled-raft is the most economical option for the given site and loading conditions. A parametric study conducted by increasing the wind speed, tower height, and pile size resulted in increase in volume of material for the piled-raft. Another study on the effect of number of piles on the settlement revealed that the increase in number of piles while keeping the size and length constant, resulted in significant decrease in settlement up to certain number of piles and thereafter the addition of piles had negligible contribution in reducing the settlement.
