Question: 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.

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 table 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.
