Method for Determining Critical Slip Surface of Cohesive Soil Slope Based on the Principle of Simple Penetration Test

Figure 6

Comparison of the results obtained by the test method, FEM, and theoretical method (1 shows the critical slip surface of slope obtained by the simple penetration test, 2 shows the potential slip surface of slope calculated by FEM, and 3 shows the potential slip surface of slope obtained by theoretical calculation).
