ENG: The paper highlights combined techniques of strengthening that include geotextile
laying as well as other related advanced technologies. Subgrade construction analysis and its
modification, reinforced with the different types and options of combined strengthening were
conducted. To justify strengthening of subgrade a series of numerical calculations were made.
Simulation with software package SCAD has confirmed the experimental results. From
obtained results one can conclude that minimum horizontal displacements are observed in the
version with deepening of geotextile at 1m and vertical ones at 0.4 m. Based on simulation
results it is possible to make recommendations concerning modernization of existing
subgrade and construction of new one in complex engineering-geological conditions.
