Slope stability with vegetation
Slope stability with vegetation
(OP)
I need to discuss how possible to stablize slopes with plants? Any general tips or guidline on this topic?
Do you think newly planted trees can probably help stabilizing slopes with potential deep failure surface?

RE: Slope stability with vegetation
Properly designed and installed plantings can help with shallow stability problems and very low slopes.

GeoPaveTraffic hits the nail on the head. For any slope stability concern, you should really seek to identify the cause(s) of the problem. Once you know the causes, then you can address the stability.
A local geotechnical engineer should be consulted.
I would not just pick up the phone and call any, I would call a structural design firm or transportation design firm and ask which geotechnical engineers have the best reputation in your area for slope stabilization issues and give them a call.

I concur that any possible shallow soil is more likely to be reinforced (by specific species of grasses). With this type of vegetation, I can understand that the vegetated soil behaves like a composite material because the roots are relatively small and heavily distributed over the shallow depth.
However, using different plant (e.g. willow) to reach deeper locations, apparently the previous mechanism might partially still valid or at least the big root may work as a soil’ nail?

Yes an investigation needs to be done but for some tupes of failure as those described above ther may be every chance that deep rooted vegetation may work. I have notedthis to occur in forest clearing where conditions after would suggest the installation of deep drains etc as the ater table after deforestation moves closer to the surface. Why was the are astable before is often the question one has to pose.
Robin Sotir has done alot of work in Bioengineering and has published info in text and papers on this subject. You may wish to review some of this info.

I think the book you may be referring to is by Gray and Sortir.

While it is a step in the right direction (vegetation) it should not be considered to 'stabilize' any slope.

I also got a pamphlet in the mail, shipped- free! I'll make another post if I can remember who I called for that.
