Step 4 <br /> • Determine the ratio between the critical height(Hc2) of the soil arch within <br /> the waste and the diameter CB2) of the unsupported foundation at the base of <br /> the waste layer. <br /> B2=2r2 <br /> HB <br /> c2 (From Figure 2) <br /> 2 <br /> Step 5 <br /> • Determine the half apex angle (02) of the cone of soil within the waste layer. <br /> Hc2 =B2(Hc2/B2) <br /> 82 = Tangy'I(r2 /Hc2) <br /> Step 6 <br /> • Determine the pressure(PN)over the yielding area at the base of the soil layer. <br /> (r, 3 3 <br /> FN = l/3 y -H�T'an8�) +Y (r, =H,TanBi)l TanBr2TanB12 r2 Tan® <br /> t 2 <br /> (7) <br />
