EARTHWORKS_TYPES• CUT(ROADS,DAMS,TUNNELS ETC)–CUT SLOPES/STABILITY

• FILL(ROADS,DAMS)–FILL SLOPES/STABILITY

• EMBANKMENTS(ROADS,DAMS)–EMBANKMENT SLOPES/STABILITY

• EXCAVATIONS(DITCHES,TRENCHES,CANALS)–SLOPES/STABILITY

CUT _PURPOSE

–SLOPE STABILITY, –ROAD WIDENING,–WIN MATERIAL TO FILL,–BORROW MATERIAL TO FILL–ACCESSIBILITY_TUNNELLING
