A soil nail proposed to be installed under the conditions given below is designed against unfactored working force of 50KN. • Ground described as sandy gravel. • Soil nail installed at an angle of 10 degrees to the horizontal and 1.2 m below the ground surface. • Nail dimensions: total length = 5 m with 60% bonded, bonded diameter = 0.35 m, debonded diameter = 0.15 m Assuming parameters not given and considering the water able to be at the surface, propose the suitable type of soil nail and calculate the theoretical working factor of safety of the installed nail against pull out. Also, briefly discuss what would jeopardise your theoretical predictions of the nail performance.

A contractor wants to explore using a 7U blade on a 240 hp dozer. Thematerial is a dry, noncohesive silty sand and must be moved a distanceof 200 ft from the beginning of the cut. It is estimated the material willswell 4%, from bank to loose state. Both visibility and traction should besatisfactory. Job efficiency is assumed to be equivalent to a 50-min hour.The U-blade width is 13 ft 1 in with 3.25 ft of wing width, and a heightof 5 ft 1.1 in. The wing angle is 28.0 deg. Assume an average pushspeed of 3 mph and a return speed of 4 mph. Calculate the direct costof the proposed earthmoving operation in dollars per bcy. Assume thatthe O&O cost for the dozer is $89.50 per hour and the operator's wageis $19.00 per hour plus 30% for fringes and worker's compensation.
