Control of the Stability and Protection of Cut Slopes in Flysch

Abstract

Due to the presence of different layers in the Eocene flysch in the region of Split, it is possible to determine from the petrography and engineering-geology the series where the slopes should be protected by various methods. During the construction process and then upon its completion, it is possible to use a suitable computer programme to establish the degree of the stability of the deposits by considering their composition, the position of the layers in relation to the cutting line and possible plane of failure. In addition, nine alternative solutions have been proposed for the protection of the slope which all take into account the specific features of flysch. The reliability of the selection is ensured by the proposed computer programme especially developed for this purpose.
