Displacement calculated with the Makdisi-Seed method using the upper -bound fault range for a Magnitude 6.5 earthquake. <br />2. Displacement calculated with the Makdisi-Seed method using the upper -bound fault range for a Magnitude 7.5 earthquake. <br />3. Displacement calculated with the Makdisi-Seed method using the lower -bound fault range for a Magnitude 6.5 earthquake. <br />4. -The results are based on a friction angle of 10 degrees for the base liner system within Modules 1 and 3, which is conservative <br />based on the interface shear strength tests included in Attachment A of Appendix E of the referenced report. <br />5. As an additional analysis, Section 6-6' was cut through Module 4. Bilinear failure envelope is defined in Figure B. Waste shear <br />strength defined by Kavazanjian et al. (1995) as presented by Duncan and Wright (2005). <br />6. The results are based on a multi -linear liner failure envelope defined in Figure A. <br />7. Revision 1: Module 1 section update; seismic analysis of higher PGA per DWR comments. <br />8. Revision 2: Reanalysis based on waste shear strength defined by Kavazanjian et al. (1995) as presented by Duncan and Wright <br />(2005). <br />Rev. 2, 12/3/2009 <br />
