Numerical Modelling of the Consolidation Behavior of Peat Soil Improved by Sand Columns

Prediction of the Geomechanical State of the Fixed Ground Basis of a Mining Building

“…Existing analytical methods quite accurately determine the parameters of fixing, however, they do not take into account the structural heterogeneity of the massif, are based on empirical dependencies and have limited ranges of physical and mechanical properties [5][6][7]. More accurate parameters are obtained when integrating numerical modeling and forecasting methods based on basic and local models which are able to take into account the structural features of ground base, the presence of anomalous zones with low physic mechanical properties [8][9][10]. The ground base of the building is man-made sediments composed of overburden rocks -mining waste, represented by several soil types grouped by engineering geological elements (IGE).…”

Geomechanical Substantiation of the Parameters of Injection Fixing of the Soil Bases During the Liquidation of the Emergency Condition of the Structure

“…Analytical methods of calculation are based on the classical laws of geomechanics and give acceptable accuracy of the solution only for homogeneous arrays and simple of calculation schemes [6,7]. Methods of numerical computer simulation are increasingly being used to solve geomechanical problems [8][9][10]. The most widely used is the finite element method, the main theoretical and methodological positions of which are presented in fundamental monographs, and practical results are given in [11][12][13].…”
