Reducing uneven deformations of the base through the use of strip self-adjusting foundations

Abstract

The article considers the reduction of uneven deformations of the base of the foundations of a five-story building, caused by local subsidence of the soil, through the use of strip self-adjusting foundations. The dependences of settlement, subsidence and stiffness coefficient of the self-adjusting foundation base on the load acting on it were obtained. Using the obtained dependences, numerical studies of the interaction of a building with a non-uniformly deformed subsidence base were performed. The results obtained showed the effectiveness of the use of self-adjusting foundations to reduce uneven deformations of the base and ensure the operational suitability of frameless buildings on subsiding soils. The uneven deformation of the base under the given conditions was reduced by about two times due to an increase in the penetration of the foundation into the ground. At the same time, the maximum shear stresses in the walls of the building decreased by about 30%.
