Enhancement of Subgrade's Bearing Capacity in Low Water Permeable (Clay) Soils

Today's level of vibrodynamic loads performed by rolling stock should be compensated for new technical solutions in railway track construction, which ensure the minimum increase of permanent deformation during exploitation. The article presents the theoretically grounded solution for reduction of intensity of permanent deformation accumulation in low water permeable (clay) soils the bearing capacity of which is significantly changed during their excessive moisturising. The effective dewatering of such soils may be feasible when using “a coarse-grained drainage”. The authors demonstrate constructions of “coarse-grained drainages” and requirements for their calculations.
