Foundations of multistorey buildings in typical soil conditions of the African continent
The article considers the engineering and geological conditions of Western Africa. The authors pay attention to the characteristic layerings including a hard surface layer (kirassa) underlain by weak clay soils. It is shown that such layering makes it possible to use foundations with shallow depth. Mathematical modeling for the joint calculation of the «multistorey building - base» system has been performed. The results of numerical calculations allow suggesting that, under certain conditions, surface foundations can be used for construction of even multistorey buildings.
