Riprap, Flow-Through Rockfill, and Reinforced Rockfill

Mass Slope Stability• Mass or global slope stability must be considered• A slope stability analysis of deep seated failure surfaces isnecessary• Seepage forces must be included in static slope stabilityanalysis to evaluate stability of a flow-through rockfillembankment• Overtopping flow forces should be added to a slope stabilitymodel• Most computer stability tools are set up to solve these types ofproblems, but the challenge to the analyst is to accuratelyestimate the seepage forces for turbulent flow– Flow nets from a laminar seepage analysis are not applicable– More research is needed on forces induced by turbulent flow
