Calculations, analysis slope stability is very basic in design construction work in general and transportation work in particular. Currently there are many software that supports analysis this, include software SLOPE /W. Borned early, with the continuous development until now, SLOPE / W software has become very popular software and have high reliability. With SLOPE / W, you can (1) calculate coefficient of slope stability by many different methods such as cylindrical sliding surface (Odinary, Bishop, Jabu ...) or with predetermined sliding surface. (2) With ability to customize very good, SLOPE / W allows users modeling and analysis of slope stability both in the case of slope reinforcement measures such as the use of anchors, geotextile, or solutions reinforced embankment as piles of sand, rubble piles ... Since then, engineers can bring out solutions to handle safety and savings.
