Abstract

Embankment failure is a common problem in Congo Republic. Almost each year in northern part of Brazzaville City embankments are facing problems such as rupturing or landslides. Among several reasons the main causes are considered because of geologically unstable materials, inadequate method of building, seepage and sliding. The current study aims to evaluate the effect of load and influence of topographic parameters such as the gradient and height of the slope on the road embankment stability with sandy landfill in the Mfilou district, Brazzaville City (Congo republic). The evaluation of the road embankment slope stability and the discovery of the implications of topographic parameters on the embankment safety management were carried out in a hilly area. A database was created based on the site inventory from field studies complemented by experimental and desk investigation. The soils properties and values of topographic parameters were incorporated to the embankment slope model as well. So, the slope modelling was carried out in different scenarios such as different slope heights, different slope angles with and without load effect. Then embankment stability was analysed with Slide 6.0 software finding slip surfaces from limit equilibrium methods. Results showed that despite the slope instability caused by the load effect, but the variation of topographic parameters affects the embankment stability as well.
