...The high cost gasoline prices are becoming a pain at the pump, and is threatening America's units price sales for SUVs. Sales of large SUVs, which boomed earlier this year, fell 5 percent in April and May as pump prices soared, and that could be just the beginning. Neither two-buck gas nor the stress on SUVs is expected to ease up any time soon. Analysts have warn that we should not take comfort in the recent small drop in gas prices. What's really pumping up prices are factors that won't go away on Labor Day: China's growing appetite for oil, America's limited refinery capacity, the war in Iraq. Having these issues it’s figured gas had to hit $3 a gallon and stay there for six months or more before Americans would reject their Suv’s. In effect when the gas prices are this high it effects the units of sale for Suv’s . Especially for customers who can afford the biggest SUVs but think twice because of gas prices, but $2 gas is already driving buyers into smaller SUVs and cars. Interactive survey this month found that nearly 50 percent of car buyers are planning to switch to more fuel-efficent vehicles. General Motors accuses Ford of using gas prices to rationalize the double-digit sales drop of its once hot SUVs like the Lincoln Navigator. Ford counters that GM is pumping up its SUV sales with giant $6,000 rebates. Chrysler CEO Dieter Zetsche wishes his competitors would just quit bickering. "I don't think any one of us is served well by trying to talk up...

Case 2 uses H1 = 2m, H2 = 7m, H3 = 5m, and H4 = 4m. Soil below Layer 4 is considered as a rigid stratum which can control failure mechanism. Case 1 Layer 1: c’ = 3kPa, φ’ = 38°, and γ = 19kN/m3 (γsat = 20.3kN/m3) Layer 2 : cu = 25kPa, c’ = 8kPa, φ’ = 25°, OCR = 2, Cc = 0.8, Cs = 0.16, e = 1.1 and γ = 15kN/m3 (γsat = 16kN/m3) Layer 3: c’ = 0kPa, φ’ = 38°, and γ = 18kN/m3 (γsat = 19.1kN/m3) Layer 4 : cu = 40kPa, φ’ = 28°, OCR = 1, Cc = 0.5, e = 0.9 and γ = 16kN/m3 (γsat = 17kN/m3) Case 2 Layer 1 : cu = 30kPa, c’ = 15kPa, φ’ = 23°, OCR = 3.0, Cc = 0.8, Cs = 0.16, e = 1.1 and γ = 15kN/m3 (γsat = 16.5kN/m3) Layer 2: c’ = 1kPa, φ’ = 35°, and γ = 19kN/m3 (γsat = 20.8kN/m3) Layer 3 : cu = 35kPa, c’ = 5kPa, φ’ = 28°, OCR = 1.5, Cc = 0.5, e = 0.9 and γ = 16kN/m3 (γsat = 17.3kN/m3) Layer 4: c’ = 0kPa, φ’ = 35°, and γ = 18kN/m3 (γsat = 19.1kN/m3) Design the cut slopes for 12m height (Case 1) and for 7m height (Case 2), based on F = 1.3 (short-term), F = 1.5 (long-term) and F = 1.15 (seismic). There are only three options that can be used to increase F for the slope. They are, 1) reduce the slope angle; 2) reduce the slope height; and 3) dewater. The optimum design is the slope cut as less as possible. The water table change will induce the consolidation. The maximum vertical displacement due to dewatering on the slope crest must be...
