Thanks to all dears, I appreciate your efforts

Yeah, the use if softwares like Abaqus.

You should check novel approaches in analysis of slope stability with concentration on new behaviour of soil/rock.

Yes, you can use Vector Sum Method (VSM) , or rigorous limit equilibrium method

Yes, you can use FLAC 3D.

You can use Slide 3D and RS3 Rocscience

New approaches could include de Material Point Method (MPM)

Plaxis can give you interesting results too.

Since contemporary codes ask to use probabilistic approach and nothing is "more statistical" then rock mass definition, I suggest you to inspect and devolop something about geostatistical approach on rock-slope stability, for example applying COV (coefficient of variation) on different properties, how they "interact" and results.

This will help to find an approach where coefficients applied are more pertinent. (and maybe will be used in new codes...)

Thanks to all dears, I appreciate your efforts

limit equilibtium method,

Plaxis is good

subject is "new approach to analyse slope stability". According that, reading the above reported answer, I suggest to focus on:

- Garcia-Feria suggestion: MPM . You can collect the information of the researcher involved, and write them for better information or the posssibility of use that kind of software (at moment are still in study and develop);

- pay attention on the variability of the joint geometry/behaviour: take in account the Forlani answer;

- i suggest to contact the smart guys of http://www.geomechanica.com. Progressive failure on non-default fracture scheme could be an interesting point of view ;

- according of previous, tale a look on

or

that are interesting about the above reported subject on not predefined joint zone.

Bye

Rocscience Slide 2D and 3D (limit equilibrium) and RS 2D and RS 3D (finite element) programs are good to work.

Dear Ahmed!

I agree with Neil, but I would add to this list the SMR too (it is not too new method, but combining with the new RMR14 directives, can make interesting surprises).

Beside these empirical solutions I also would suggest you to use RS2 and RS3 - it is easy to work with them (and I like it in the new verions that there is possibility to define constitutive models by user and the dynamic "engine" is working better and better).

Geo 5 or plaxix 3d

Ahmed Mohamed , I suggest that you be on the look out. Find a case study possibly in the surface mine enviroment . The mine should be equiped with the real time slope monitoring radar. Study on the progressive failure of the slope which has a non default fracture by numerical simulations (I recommend the use of FLAC 3D), compare the numerical simulations results with the field monitoring information.

Dear Ahmed

Analyzing the slope stability in soil and rock is totally different.

In rock mass, depending on the discontinuity condition, DEM would be a reliable approach. There has been a dramatic advancement in DEM analysis of rock slopes (e.g. DFN-DEM) in recent years. However, there are still plenty of room to improve previous studies. For instance, coming up with a new constitutive model that would be able to link the model parameters to geometrical and morphological characteristics of rock joint could be a novel approach. Such models would be implemented it in DEM codes to simulate the rock slope stability more realistically. Incorporating new reinforcement model(s) (e.g. rock bolt) would also augment the response of DEM simulations.

I have little experience in soil slope stability, but FEM and FDM has proved to be promising tools. You could work on the possible gaps in the current constitutive models and perhaps you'll be able to improve their behavior.

Best regards, Mahdi

Truly agreed with Mahdi Saadat.

Agree with Lucas and Mahdi Saabat.

I also suggest you DDA (discontinu defeormation analysis) method developed by Shi. This is a very interesting method for the analysis of rock slope stability.

Regards

Plaxis 3D or RockScience S/Ws. DIPS would be helpful for preliminary kinematic analysis.

Let's break down your question:

A. Numerical approach:

(i) For equivalent rock slope (continuum model) stability analysis, use: (a) FEM: Plaxis 2D or 3D, RS2 or RS3, (b) FDM: FLAC 2D or 3D, (c) LEM: Geo5, Geoslope, Slide 2D or 3D.

(ii) For jointed rock slope (discontinuum model) stability analysis, use: (a) DEM: UDEC (2D), 3DEC (3D), (b) Kinematic analysis: DIPS, Stereoplot.

(iii) For debris slope (granular material model) stability analysis, use: (a) PFC 2D or 3D, (b) COMSOL.

B. Experimental approach:

You may prepare an experimental tank with appropriate dimensions to nullify boundary effects, then prepare slope with slope materials like either debris material or overburden soil and use artificial or synthetic rock like lean concrete (for weak rock) or high strength concrete (for strong rock) as the bedrock. Please maintain the in-situ density in the model slope also to simulate near field behavior. For inducing slope failure, you may use artificial rainfall (by sprinkler system on top of tank) or you may put the experiment tank on a tilting platform and induce failure by gravity.

Hope the above answer helps you. All the best.

I don't have any. Infact I am planing to start my PhD. Which I am looking at the topic of slope stability, soil modeling or site characterisation for my PhD program. Please send me mail if you have any guide for me to [email protected] or [email protected]. I Will also be grateful if you can link me up with scholarships that you know.
