a. VA granular soil has a saturated unit weight of 18.0 kN/m³ and an effective angle of shearing resistance of 30°. A slope is to be made of this material. If the factor of safety is to be 1.25, determine the safe angle of the slope: (i) when the slope is dry and (ii) if seepage occurs at and parallel to the surface of the slope. b. The factor of safety of a clay slope and the indicated slip circle shown in Figure Qu. 5 is considered inadequate. In order to increase the factor, the slope is to be altered by removing the shaded part of the slope. Determine the percentage increase in the factor of safety after 3 of 6 this alteration.
