Design Optimization of Piled-Raft Foundation for Tall Wind Turbine on Clayey Soil
A geotechnical design optimization procedure for piled-raft foundation to support a 130 m tall wind turbine in a clayey soil is presented in this paper. Based on the initial geotechnical design it was found that the final design was controlled by differential settlement which was later considered as the response of concern for design optimization. A parametric study was also conducted to examine the effect of undrained cohesion and wind speed (random variables) on the design parameters (number and length of piles and radius of raft). Finally, a robust design optimization was conducted using genetic algorithm coupled with Monte Carlo simulation considering the total cost of foundation and the standard deviation of the differential settlement as the objectives. This procedure resulted in a set of acceptable designs called Pareto front which can be used to select the best design for a given performance requirement and cost limitation.
