toppling failure

(OP)
I performed stereographic projection, but poles distribute in the toppling envelope. Hence, I must execute limit equilibrium analysis
How do I?

RE: toppling failure

Before considering whether need to perform further analysis, I think further information regarding the studying rock feature is required. Moreover, caution should be given to use of conventional stereographic analysis and generalised assumptions about joint sets, as the stereplots may obscure the variability of joints orientation.

My questions are:

The rock joints data is determined by geoloigcal mapping on site or insitu field test such as impression packer test and televiewer?

The rock feature is a new formation slope or existing one? For an exsiting rock slope, the designer should rely more on field mapping and less on the stereoplots!
