How to built a stereographic net
How to built a stereographic net
(OP)
I'm now doing on my thesis and the topic is 'Engineering Geological Properties'. Therefore, I must go to the site at one of our local new developed highway to take reading about dip and strike inclination, dip and strike direction and minor and major set of joint and fault. So, after all this, i must develope a stereographic net using the data. But the problem here is i don't have the data about angle of friction. So, my question is , can i built a complete stereographic net without the data about angle of friction depending oin the data about joint and faults only?

If you are analyzing stability, you will need the angles of internal friction of each fracture orientation set. gbbycu gave a good description. I do at least six or more repetitions of each fracture set from different samples to get some idea of a mean and variance.
It starts to get very complicated for critical slopes. You must also consider roughness and fracture continuity in the analysis of stability.
