As terran, what are the most common techniques to block off the entrance ramp to your base?
There are many different arrangements of structures or units that can be used to block off the entrance to a base to prevent a zealot push or zergling rush. The obvious answer is barracks and a supply depot, but I've also seen people barricade their entrance ramps with all supply depots, or with bunkers.
If barracks are being used, the direction of the ramp and other factors makes a difference, since placing the barracks in the wrong place can prevent you from building add-ons later on.
What are the most common techniques used for positioning an early-game terran ramp barricade, and how does the ramp direction (or cliff edge) and the information you get from scouting influence it?

I assume you're talking about the first ramp wall and not the B2 wall.
The wall depends on two things : the ennemy BO and the map. Depending on the starting spot (especially with new maps) the ramp is more or less wide, which is why some ramp with only supply depots or add one or two barracks.
if you scout ennemy strategy, different walls are possible (for high level plays of course, under diamond / top plat you can wall your first base with two supply and a barrack almost all the time).
You might want to wall with a bunker if the ennemy goes for a all in.
