Africa is facing the challenge of generating more power to meet existing and future demand. Currently, about one-half Africa's total population is lacking access to electricity. However, the continent is well endowed with renewable energy resources; it is estimated that about 35% of the world resources for wind energy are located in the continent. There are many challenges which hinder the development of infrastructure for wind energy in Africa. Designing suitable foundations to sustain the loads typically applied by wind turbines represents a particular challenge. Most potential locations for wind turbines in Africa are in tropical zones where fluctuation in ground water level is severe. The cycling of water levels means that many deposits of interest are unsaturated for at least part of the year. Unsaturated soils exhibit complex mechanical behaviour, coupled to changes in water content. This research aims to provide design for the foundations of wind turbines in unsaturated soils.

非洲正面临着产生更多电力以满足现有和未来需求的挑战。目前，大约一半的非洲总人口无法用上电力。然而，非洲大陆拥有丰富的可再生能源；据估计，世界风能资源的约35%位于非洲大陆。非洲风能基础设施的发展面临许多挑战。设计合适的基础来承受风力涡轮机通常施加的载荷是一项特殊的挑战。非洲风力涡轮机的大多数潜在地点位于地下水位波动严重的热带地区。水位的循环意味着许多利息存款至少在一年中的部分时间处于不饱和状态。非饱和土壤表现出复杂的机械行为，与含水量的变化相结合。本研究旨在为非饱和土壤中风力涡轮机的基础提供设计。
