This article discusses the problem of the instability of road embankments. Two types of landslides located in various geotechnical conditions were analysed. The first case is where the stability of the road embankment itself is lost, in which the soil layers under the embankment have no influence. In the other case, the instability of the embankment is connected with landslides of the soil on which a given embankment is situated (slope stability loss). The authors proposed original solutions which were later on verified by MIDAS GTS NX®. The conducted studies show that the proposed protection strategies for both slopes are effective, thus yielding a high coefficient of general stability (FoS).
