Slope stability software
Slope stability software
(OP)
I am looking for the best slope stability software, for the best price, that also calculates fos for reinforced slopes as well as for seismic loading conditions.

"It is argued that the the finite element method of slope stability is a more powerful alternative to traditional limit equilibrium methids and its widespread use should now be standard in geotechnical practice".

We also use the latest Slope/W (www.geo-slope.com) which is on the order of 3,500 or so. Complicated but great technical program with great Autocadd integration, and great graphics. Will also do probabilty analysis, etc.

If you are looking for cost effective programs, GStable (which runs with STED, mentioned above) is a good alternative and easy to understand and run.
I cordially disagree that everyone should be running finite element slope stability programs. Garbage in - garbage out.
Hope this helps.

Or how about discontinuity layout optimization, which seems to be simple like limit equilibrium but general like finite elements. LimitState:GEO is based on this, see: http://www.limitstate.com/geo/examples

I think that FEM is most likely a waste of time. Most engineers and geologists seem to have a hard time coming up with a realistic subsurface model of a site as it is. Any engineer that has spent a lot of time looking at open excavations knows how variable a site can be, at least here in California anyway.
As a wise old geotechnical engineer once reminded me....engineers evaluate slopes, not computer programs.

However, I have used SLIDE and SLOPE/W and both seem to have similar features but sometimes dealt with in different ways, e.g. anisotropic strength functions, and one method may be preferable to the other depending on your requirments. SLIDE is however considerably cheaper and I found it much easier to use, particularly the CAD import / interface but then I was already familiar with PHASE2. Technical support from Rocscience (SLIDE) is excellent but I have not tried it with SLOPE/W. Both cater for reinforvcement and seismic loading.
I used GEOSTRU some time ago and it was good for the price. Although such cheaper programmes are adequate for simple analyses, check if they have the facility for Hoek-Brown parameters, probabilty, sensitivity, strength functions etc. if these are likely to be required.
With regard to "Garbage in-Garbage out", yes, elastic parameters are not easy to define but if you are using plastic analysis and Mohr Coulomb parameters with FE, these are the same garbage that you would input into limit equilibrium. As usual, it is horses for courses, sometimes limit equilibrium analysis gives more flexibility to analyse a particular problem.

How about Limitstate:Geo and new SVSlope?
Thanks in advance
RE: Slope stability software
I don't know much about SVSlope but have used LimitState::GEO quite a lot recently. Like finite element packages it can be used for pretty much any geometry of geotechnical problem - not just slope problems. But unlike finite elements there are very few input parameters to worry about and it is very quick and easy to use (and the output is clear too). The solutions generated are rigorous plasticity ones, rather than limit equilibrium.
For slopes the biggest thing to get your head around is that it reports a factor of safety on an applied load (can be self weight and/or surcharge), rather than a traditional global factor of safety (i.e. resistance/disturbing action). This is initially disconcerting but fine if you are designing to the new Eurocode 7 (using design approach 1), which applies partial factors on material strengths, and you just need to check that the factor on the load is >1.
Finally - LimitState:GEO does do nails, but apparently no seismic capability yet...
