This presentation will discuss a procedure to assess whether a liquefied strength or liquefied strength ratio should be applied to a zone(s) along a potential failure surface in a static or dynamic stability analysis to assess the flow failure potential of dams and embankments. The procedure consists of the following five main steps: (1) assess static liquefaction potential of segments along failure surface, (2) assess seismic liquefaction potential of these segments; (3) if liquefaction is not triggered, assess the magnitude of shear-induced pore-water pressures in each segment; (4) assign a liquefied strength to zone(s) that experience liquefaction or significant pore-water pressure generation; and (5) conduct a post-triggering stability analysis to assess flow failure potential. This procedure will be illustrated using examples.1.0 PDH
