Why the surface pass the foundation pile in slope stability
Why the surface pass the foundation pile in slope stability
(OP)
Dear all
I'm modelling a slope in rocscience slide6 slope stability.
I'm Set a width 1m concrete wall in the model to simulation foundation pile
but Why the surface will pass the foundation pile and the safety factor will increase?
Thanks

All this will do is force the failure plan to extend below your pile tip.
In short, limit equilibrium stability programs are not a good way to model retaining walls. Soil nail anchors, etc yes, embedded retaining walls no IMO.

To respond to why the FOS increased you want to look at the graph which shows you the shear resistance for each slice along the failure plane with and without the pile for the exact same slip surface.

In addition if you need/want to model a pile in a 2D software program, my suggestion is to model the pile as a reinforcing load acting perpendicular to the slide plane. Determining the appropriate load is difficult, but can be done using other software programs such as LPile.

I will try other analysis software for slope and pile modeling
