In excavation for a wall footing, the water table level was lowered from a depth of
1.0 m to a depth of 3.0 m in a clayey soil deposit. Considering that the soil has a
water content of 28% when it is fully saturated, and above the water table the (dry)
unit weight of the soil is 17 kN/m³. Assuming initially that all of the soil above the
water table is dry, then compute the following:
1. The effective stress at a depth of 4.0 m after the lowering of the water table.
Take Gs = 2.68. (Hints: w*Gs=Sr*e)
2. The increase in effective stress at a depth of 5 m.
(You also need to plot the values of total vertical stress and effective vertical stress
against depth before and after lowering the water table.)

- 5.6 A section of highway has the following flow- density relationship q = 50k - 0.156k2 [with q in veh/h and k in veh/mi]. What is the capacity of the highway section, the speed at capacity, and the density when the highway is at one-quarter of its capacity?arrow_forward8.20 Two routes connect a suburban area and a city, with route travel times (in minutes) given by the expressions t₁ = 6 + 8(x₁/c₁) and t₂ = 10 + 3(x2/c2), where the x's are expressed in thousands of vehicles per hour and the c's are the route capacities in thousands of vehicles per hour. Initially, the capacities of routes 1 and 2 are 4000 and 2000 veh/h, respectively. A reconstruction project on route 1 reduces the capacity to 3000 veh/h, but total traffic demand is unaffected. Observational studies note a 35.28-second increase in average travel time on route 1 and a 68.5% increase in flow on route 2 after reconstruction begins. User-equilibrium conditions exist before and during reconstruction. If both routes are always used, determine equilibrium flows and travel times before and after reconstruction begins.arrow_forward8.19 Three routes connect an origin and a destination with performance functions t₁ = 8+ 0.5x1, t2 = 1 + 2x2, and t3 = 3 + 0.75x3, with the x's expressed in thousands of vehicles per hour and the 's expressed in minutes. If the peak-hour traffic demand is 3400 vehicles, determine user-equilibrium traffic flows.arrow_forward

Suppose a household has five members (three of whom work) and an annual income of $100,000.
