Question

You may also assume a unit volume of soil, V, 1m3, for this problem. (5) Supplemental Homework Problem Soil from a borrow site is used to place 2000 cubic meters of fill at a construction site. The soil properties for the borrow and fill are given below. Given: Borrow: Fill: (a) (b) Change in void ratio Ae between the borrow and fill 1690, Yr-173kN/m2 Gs 2.72 w w-1696, r,-181kN/m3 Find: Vr from borrow to place 2,000 m3 of fill Use the phase diagrams and calculate all weights and volumes for each soil phase (air, water, solids) of the borrow and the fill. Note that Vw and Ww from borrow is the same as Vw and Ww in fill, because w-16% for both. (SEE NEXT PAGE FOR THE PHASE DIAGRAMS)
