I am a begginer performing a rock slope stability analysis
I have the topographic map showing the slope geometry and couple of intersecting faults existing in the slope region.
In order to perform failure potential for wedge and planner assessment. I only have topographic map showing the slope on which the faults are plotted and rock strength data;
Plesae verify the following:
I need to extrat from the map the following
-Slope face Dip : this is I beleive the slope angle with the horizontal (I can easily get from the map)
-Slope face dip direction: how I get this from the topographic map: Should I measure the angle of the line representing the slope crest (on the topographic map) with the north and add 90 degree to it, as geologically defined.
-Fault dip direction: should I measure the angle of the fault with the north and add 90 degreeas as geologically defined
-Fault dip: how can I get that from the map.
e I also projected couple .
