3.3.4.2 Deformation Analysis <br />Yield accelerations computed in previous analyses are expected to be conservative, because <br />tailing have de- saturated and consolidated relative the conditions assumed in the original design. <br />Original design analyses computed an estimated settlement of 1 to 3 feet based on computed <br />yield accelerations. The worst -case yield accelerations are on Failure Surfaces 4 and 5 in <br />Figure 5 (10.6% and 11.3% of g, respectively). These settlements are reasonable for the <br />condition of saturated tailing that existed during active tailing deposition. However, under <br />current conditions of drained tailing, both of the critical failure surfaces are anticipated to be <br />entirely within unsaturated materials so the previously estimated settlements appear <br />conservative. <br />San Luis Project Miller Geotechnical Consultants <br />Tailing Dam Data Report 21 February 2014 <br />
