An assessment of current methods for stabilising steep cut slopes by establishing vegetation.
The stabilising of cut slopes in civil engineering projects has been the major problem since the commencement of early construction procedures. This problem has been made more acute where erodable soils exist and rainfall intensities result in excessive run-off. Engineers have over a period of time independently devised and adapted certain methods with varying degrees of success. This paper examines the various current methods that are being used throughout South Africa and assesses the merits of such methods. Furthermore, factors that have an overriding influence on the success of a particular method in a certain set of circumstances are analysed. Cost comparisons are produced to assist in judging the economic feasibility of the different methods.
