Numerical simulation of station tracks on soft soils

摘要

The article presents the results of computing simulation of station tracks on soft soils represented by post-glacial clay sediments. As stabilizing measures, the article considers the dumping of a pilot berm with the determination of the holding time for each layer according to the criterion of the stability factor and base strengthening with a high-strength woven geotextile. An analysis has been conducted with respect to laboratory and field tests, the parameters have been selected for soil models, and virtual laboratory tests have been performed with a view to verify the repeatability of the models. When performing calculations in the Plaxis software package, Soft Soil soil models have been used with the behavior type Undrained A.
