ABSTRACT
Extension of the Bishop and Morgenstern Slope Stability Charts As stated earlier, Bishop and Morgenstern (1960) charts or tables cover values of e'lyH equal to 0.000, 0.025, and 0.050 only. These charts do not cover the values that are normally encountered in natural slopes. 0' Connor and Mitchell (1977) extended the work of Bishop and Morgenstern to cover values of e/lyH equal to 0.075 and 0.100 for various values of depth factors nd• The method employed is essentially the same as that adopted by the earlier authors. The extended values are given in the form of charts and tables from Figs. B.7 to B.14 and Tables B7 to B14 respectively in Appendix B.
