SLOPE STABILITY ANALYSIS <br />The analysis of the dike slope was performed according to Bishop's method of slices with the <br />program SB-Slope, an MS-DOS based program. SB-Slope performs Bishop's method of slices <br />on a failure circle selection grid, and each failure circle was analyzed with 50 slices. <br />The failure circles were determined by analyzing numerous circles over a grid from (-30 ft, 100 <br />ft) to (90 ft, 170 ft) as seen in Figure 2. A center for a failure circle was analyzed at a 5 ft <br />interval on the grid. Radii was allowed to vary from 0 ft up to 60 ft at a 4.0 ft increment. <br />(-30,170) <br />Bishop's method: <br />Failure circle <br />Selection grid <br />(-30,100) <br />(90,170) <br />(90,170) <br />Figure 2 - Selection Grid <br />The results of the Bishop's method of slices are included as Appendix B. <br />Tri County Dike Slope Stability Jan 08 <br />5
