Methodology for predicting settlement of waterlogged foundations of electric furnace foundations at Aksu Ferroalloy Plant

Abstract

The authors proposed a new method for predicting precipitation of flooded foundations after their construction. The developed technique makes it possible to determine the required capacity of the non-soaked soil in the bearing layer of the base, as well as to choose the optimal depth of water reduction. This forecasting technique provides an opportunity to make changes to the values of the compression modulus of soil deformation and conversion coefficients to obtain more accurate values of the stamp module.

The main research topic is related to the complex analysis of the bases and foundations of electric furnaces No. 61 and 63 in the melting shop of the Aksu ferroalloy plant. In the course of the work, engineering-geological and hydrogeological surveys, geophysical studies, as well as an analysis of the technical condition of existing foundations were carried out. Based on comprehensive scientific and technical research, a new calculation model has been developed that allows you to predict the precipitation of buildings, taking into account the long-term water saturation of soils in the base. In addition, the reliability of the existing foundations of electric furnaces No. 61 and 63 and the possibility of their subsequent reconstruction in the context of the upcoming renovation were assessed.

Thus, this study and the developed new methodology for analyzing the sediment of flooded foundations and assessing their reliability makes an important contribution to geotechnical design. The results of this work can be applied to optimize the design and renovation of buildings and structures based on more accurate consideration of the impact of groundwater on the foundations.
