To assist Henderson Mill personnel in performing slope <br />stability analyses for the existing study sections, a User's Guide is attached as <br />Appendix A. This guide leads the user through each section of the input file .and how <br />the file should be modified to handle changes in phreatic surface and raisers of the <br />embanloztent. It also describes how to run UTEXAS3 and GRAPHICS including some <br />of the difficulties that can be encountered and how to avoid these. For a comprehensive <br />and detailed description of the various aspects of UTEXAS3 and GRAPHICS, the user <br />documentation provided with the programs should be referred to. <br />.~ <br />_~ <br />~~ <br />~~ <br />~~ <br />~~ <br />~~ <br />Input files that were created for each of the stability analyses presented above are <br />presented in Appendix B. The first five of these input files are for the existing height <br />embankment study sections. Adjacent to the points in these input files that define the <br />phreatic surface at piezometer locations, we have labeled which piezometer these points <br />correspond to. This information should be referred to when making future slope: stability <br />analyses where the phreatic surface is to be shifted in response to changes in pii;zometer <br />water levels. <br />Output files that were created for each of the stability analyses presented above are <br />included in Appendix C. The diagnostics found at the end of several of the output files <br />were examined to confirm the validity of solutions. <br /> <br />u~ni~ m•n-svRrr 3-8 <br />
