Earth is required to be excavated from borrow pits for building an embankment as shown in the figure below. The moisture unit weight of the borrow pits is 18 kN/m³ and its water content is 8%. Estimate the quantity of earth required to be excavated per meter length of embankment. The dry unit weight required for the embankment is 15 kN/m³ with a moisture content of 10%. Assume the specific gravity of solids as 2.67. Also determine the degree of saturation of the embankment soil and the volume of water in the embankment.

Your company has won a contract to provide and compact the fill material for an earth levee (an embankment built to prevent overflow of a river), with the dimensions shown below. The levee fill is a silty clay soil to be compacted to atleast 95.1% of maximum standard Proctor of dry unit weight= 109lb/cu.ft at an OMC of 18.6%. Your borrow pit has a silty clay with an in-situ moist density of 112.6lb/cu.ft at 18.1% water content and a Gs = 2.679. When the soil is excavated and loaded on to your trucks, the void ratio of the material is e = 1.46. Your trucks can haul 401 cu.ft of material per trip. DETERMINE THE FF AND SHOW COMPELETE SOLUTION. ALL FINAL ANSWER WILL BE IN 3 DECIMAL PLACES. 1. Determine the volume of fill required for the levee in cu.ft 2. Determine the volume required from the borrow pit in cu.ft 3. Determine the required number of truck loads.

Suppose that you are a Project Engineer on a Dam project. The volume of soil required at the dame site is Vd=100,000m3. The final void ratio (ed) is 0.80. Your boss, the Project Manager delegates to you the important decision of buying the earth fill from one of three suppliers. • Supplier X sells fill at OMR. 0.200/m3 with e = 0.90• Supplier Y sells fill at OMR. 0.120/m3 with e = 2.00• Supplier Z sells fill at OMR. 0.150/m3 with e = 1.60Evaluate and select the best supplier based on your knowledge about soil compaction.
The Tuttle Creek Dam in Eastern Kansas is an earth-fill dam which has a height of 137 feet, a top width of 50 feet, a bottom width of 1,050 feet and a length of 7,500 feet. The dam consists of clay that has a shrinkage factor equal to 0.90 and a load factor of 0.79. Compute the equivalent bank volume of clay that would be taken from borrow to build the dam. Compute the equivalent loose volume of clay that would have to be hauled from the borrow to the dam.
