Abstract
Purpose: Prediction of geomechanical state of soft-soil foundation of buildings before and after compaction, reinforcement or stabilization. Calculation of parameters of pressure injec-tion while stabilizing the soft man-made soil foundation, development of recommendations for parameter adjustment of pressure injection.
Methods: Numerical methods and computer mod-eling of the soil foundation using the finite element method for studying its geomechanical state of a mining building with regard to heterogeneities of the local geological structure and changes in the physical and mechanical properties of soils.
Research findings: The obtained results are based on engineering and geological surveys of the soil foundation of the mining building composed of man-made bulk soils. The stress-strain state of the soil foundation is simulated. As a result of injection compaction the geomechanical state of the soil mass chang-es.
Practical implications: Recommendations are given for the parameter adjustment of the injection method. It is shown that the pressure injection method is undoubtedly effective for the soil stabilization for buildings.
