3. A reinforced concrete box culvert of prismatic form with a clear vent- way of 3.5 by 3.5 m is required for a road crossing. The box culvert has to support a super imposed dead load of 8 kN/m2, and a live load of 50 kN/m². Density of the soil is 18 kN/m³, and the angle of repose of the soil is 30°. Adopting M-20 grade concrete and Fe-415 grade tor steel, design the box culvert and sketch the details of reinforcements in the box culvert.

For the foundation grounding of a building, it is planned to make a 40 m x 50 m network with a 90 mm2 cross-section conductor embedded in a uniform soil environment with a specific resistance of 100 ohmmeter, 0.5 m deep, and the mesh consisting of 10 m spaced meshes.a) Find the spreading resistance of this earthing system with the Sverak method.b) If piles with a length of 2 m are driven into four corners of the foundation earthing, what will be the total spreading resistance? Calculate
A rectangular flume made of planed timber(n=0.12) has a slope of 1m per km. If the flume will have width of b and depth of y, which of the two flumes will have the greater discharge and which will require less lumber? (Fig. 10.6.2) (Hint: Compute for Q and Rh)
Regarding geotextiles used in separation, what is the required burst pressure of a geotextile supporting 75-mm maximum-size stone and heavy trucks with a tire inflation pressure of 1000-kPa? Use (where p’ = the pressure at the geotextile interface and p = the inflation pressure); a cumulative reduction factor = 2.0; and a factor of safety = 2.0.
The Town of Jackson Engineering Department has an earthen dike through which a circular concrete culvert has been constructed to convey storm water from one side of the dike to the other side of the dike. The circular concrete culvert has a free outfall. The culvert is 60 feet long on a 2.00 % slope and is 30 inches in diameter. The culvert entrance will project from the embankment. Use an orifice coefficient (Co) of 0.62 for a sharp-edged entrance. Create a rating table that correlates the culvert discharge to the depth of the headwater, from 3 feet to 6 feet in 0.25 feet increments. The Engineering Department would like to know the culvert discharge rate based on the depth of the headwater so that they can conduct long-term planning (development, infrastructure improvements, open space, etc.) on the upstream and downstream sides of the dike. Cite any references used.
A horizontal impervious floor of length 20 m is provided with a sheet pile of 5 m depth at its downstream end. The head causing flow is 3 m. If the specific gravity of soil is 2.68 and void ratio of soil is 0.70 then the factor of safety against piping (by Khosla's theory) would be (Correct upto 1 decimal place).
