Optimizing nonlinear soil body models for geotechnical conditions of Saint-Petersburg

The quality analysis of physical and mechanical parameters of soil body acquires increasingly higher topicality as complexity of construction engineering grows and it is required to carry out nonlinear modeling of soil mass. This study addresses the site survey data obtained in the territory of Saint-Petersburg. The procedures to determine quality index of soil samples are discussed, the influence of quality of samples on their physical and mechanical parameters is assessed. The procedures for determining overconsolidation factor and natural stress state formation in soil mass are compared. The influence of structural discontinuity of test samples on their volumetric stiffness assumed in nonlinear soil body models is estimated. The consolidation test curve is corrected using two graphical methods, and the influences of these methods on initial geomechanical parameters are compared. Based on the performed analysis, the procedure is proposed for the determination and optimization of input parameters for modeling consolidating soil bodies using geotechnical engineering simulation PLAXIS. The quality of soil mass in the area of Saint-Petersburg is described, and the impact of different parameters on the model calibration and its agreement with the lab-scale test data is discussed.

Keywords: overconsolidation factor, nonlinear models, soil mass, Plaxis, SoilTest, triaxial testing, compression testing, consolidating soil body model, numerical modeling.
