  • An integrated approach in the selection of design solutions for strengthening soil foundations in the reconstruction of buildings in the Rostov region

    The problems of the operation of buildings on subsidence soils of the Rostov region are considered. A brief analysis of the methods used to consolidate the soil. Concrete examples of the use of cementation and silicatization of soil bases in the development of reconstruction projects for buildings in the cities of Shakhty and Taganrog, Rostov Region are given. An integrated approach to the choice of technology for fixing the soil base of reconstructed objects is proposed, which provides for the simultaneous consideration of the following factors: - basic physical and mechanical properties of soils; - mineralogical composition of soils; - change in the state of the soil base during the operation of the building (local decompression, erosion, chemical and mechanical suffusion, etc.); - chemical composition and groundwater level, forecast of their change; - terrain, the danger of activation of landslide processes; - the presence of retaining walls and other retaining structures in the zone of influence, assessment of the loads on them in the process of consolidation; - the technical condition of building structures of the building, including its underground part and the blind area; - the status of the reconstructed object. With special care and precaution, it is necessary to choose the technological and design parameters of soil consolidation for cultural heritage sites of federal or regional significance; - technical and economic indicators.
