Q1 The rock slope has been mapped and analysed. The data of slope geometry and rock parameters tabulated in Table 1. The face slope facing toward south and the upper slope is flatted. The discontinuity sets are as follow (dip direction / dip angle); set 1: 10/46', set 2: 190 /40°, and set 3: 140/70°. Parameters Values Face slope dip angle 65° Slope height 50 meter Slope length 150 meter Unit weight of the rock 25 kN/m3 Depth of tension crack 2 m Unit weight of water 9.81 kN/m³ The cohesion of all discontinuities 50 kPa Friction angle for all discontiuities 30° ) Calculate the factor of safety for the planar failure mode when the tension crack is completely filled with water.
