Project Name: Forward Landfill <br />Project Location: Manteca, CA <br />Liner Slope Stability: S. Lewis <br />2:1 Side Slope Anchor Trench March 24, 2006 <br />This file is A:\SLOPBASE regarding the liner slope stability. <br />The purpose of this calculation is to evaluate the factor of safety <br />for the proposed configuration. Edit data in columns B-H, K & L. <br />Residual strength values will be reduced by the selected FS. The actual <br />FS will be the one where the anchorage strength equals zero. <br />Copyright Stephen J. Druschel 1992. <br />Method Reference: <br />Druschel, S.J., and Underwood, E.R. (1993).
