15.14 Refer to Problem 15.13. What is the critical height of the slope? What is the nature of the critical circle?
Transcribed Image Text:15.14 Refer to Problem 15.13. What is the critical height of the slope? What is the nature of the critical circle?
15.13 Using the graph shown in Figure 15.13, determine the height of a slope (I vertical to 2 horizontal) in saturated clay with an undrained shear strength of 38 kN/m and a unit weight of 18.7 kN/m. The desired factor of safety against sliding is 2.5. Given: D = 1.50. For B> 53": All circles are toe circles. For B< 53": DH Toe circle Midpoint circle Slope circle (a) 0.3 0.2 - 53 D = 4.0 0.1 1.2 1.0 15 2.0 0.0 90 80 70 50 40 30 20 10 Slope angle, B (deg) (b) Figure 15.13 (a) Definition of parameters for midpoint circle type of failure; (b) plot of stability number against slope angle (Adapted from Terzaghi and Peck, 1967.
