Example 3.2: Analyze the stability of the concrete gravity dam 68 m high shown in Figure 3.50 for the following conditions. The ice force is 30 kN/m. Friction coefficients between concretes, and concrete-foundation are 0.75. Compressive and shear strengths in concrete are 30 MPa and 6 MPa, respectively. Compressive strength of the foundation material is 90 MPa. Drainage system may reduce the uplift force by 50%. There is no tailwater. The earthquake coefficient is kk,-0.1. The specific weights of concrete and water are 24 kN/m³ and 10 kN/m², respectively. The required safety factors can be taken as those of the extreme loading case.
