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 installe nail against pull out. Also, briefly discuss what would jeopardise your theoretical predictions of the nail performance.

Question

Transcribed Image Text: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.
