Calculation of Soil–Transport Structure Interaction
The paper considers soil–transport structure interaction. Soil deformations, completely defining deformations of a road embankment, require an accurate prediction with a help of effective models of soil behavior, which take into account its non-linear and rheological behavior. There is given a visco-plastic model of behavior of soil of small and medium degree of lithification, which allows predicting development of deformations of transport structures in time. It is demonstrated that settlements of structures are defined not only by deformations of consolidation but also by deformation of form change. The authors implemented the soil model in the software complex FEM models, which is an import-substituting domestic production overtaking capacities of western analogs according to the speed of solution of non-linear and rheological problems. The paper shows the results of verification of the software for meeting the results of monitoring of a renown site of transport construction—the dam for protecting St. Petersburg against floods, which test grounds served for long-term investigations of the process of soil deformation under different draining conditions.
