Using geosynthetics for soft ground stabilization in the approach to the Volhov River Bridge

This paper highlights recent experience of the geosynthetics applications during the recon-struction of the roadbed on the soft grounds. The piles foundation was used to reduce the difference set-tlements on the approaches to the bridge across the Volkhov River. The stripe drains are used to acceler-ate the settlement and reducing pore pressure in the foundation soils of embankment. Laying mattress, which was made from uniaxial geogrid, has enabled to increase the carrying capacity of the foundation. The lightweight embankment from XPS blocks have not changed the load based on the existing subgrade, which allowed refusing from the base reinforcement.
