ABSTRACT
Design and construction of foundations for wind turbines in the Rann of Kachchh pose several geotechnical challenges. These coastal deposits consist primarily of loose sands, low-plastic and non-plastic silts with high moisture content as well as soft clays to substantial depth. The area being in Earthquake Zone V with high seismic vulnerability, there is a potential for liquefaction of the loose sands and the saturated loose silts. The paper presents a case study of geotechnical investigation performed at one wind turbine foundation to characterize the engineering properties of the non-plastic silt that was prone to liquefaction during earthquakes.
