ABSTRACT

The subject of the paper is a landslide process near Sofia, which endangers the international railway
traffic to Greece. Sliding arises out of a lack of measures for drainage. The intensive landslide process
should be overcome in three stages: 1/ prompt measures for the active slide prevention combined with
earthfill abutment with a retaining wall; 2/ building of drainage structures, and 3/ reinforcement of the
earth bed under the railroad.

The approach for getting the landslide processes under control is demonstrated in a project where the
author is chief designer. Important recommendations are ensuing from this project outcomes for the
design of strengthening structures, design of drainage structures, and reinforcement of the earth bed
with the help of geotextiles and geomeshes.
