Find the total stress ( σ ) , pore water pressure ( u ), and effective stress ( σ ′ ) at points A , B , C , and D . Plot the variation of stresses with depth.

Question

A four-lane undivided multilane highway (two lanes in each direction) has 11-ft lanes, 4-ft shoulders, and 10 access points per mile. It is determined that the roadway currently operates at capacity with PHF = 0.80 and a driver population adjustment of 0.9. If the highway is on level terrain with 8% large trucks and buses (no recreational vehicles) and the speed limit is 55 mi/h, what is the directional hourly volume?

For automobile, gasoline is a complex mixture of relatively volatile hydrocarbon blended for use in spark-ignition engines. Every time fuel is burned, the carbon is converted to carbon dioxide (CO2), the natural end product of combustion. If we approximate the chemical ormula for gasoline by the compound octane (C8H18) with a density of 739 grams/liter, the stoichiometric reaction for complete combustion is: C8H18 + 12.5O2  8CO2 + 9H2O Thus, for every mole of C8H18 fuel that is burned, eight moles of CO2 are produced, alon with nine moles of water vapor. Estimate the CO2 emission in grams per mile for a car getting 12 km/liter of gasoline.

An urban county with an area of 1,000 mile2 has an estimated 18 million miles of vehicular traffic per day and has a large power plant. The power plant produces 350 MW of electricity at an efficiency of 39%, burning 10,000 Btu/lb coal. The vehicle emission factor for VOCs is 6 grams/mile; the coal-fired boiler emission factor for VOCs is 1.4 lb/ton coal; biogenic emission of VOCs is 0.4 kg/km2 -hr on the average. Determine the total emissions of VOCs in tons/day from all sources (mobile, power plant, and biogenic).
