Shrestha,

making your question more specific will help your colleagues understand what you are looking for? Are you talking about hazard mapping or something else? Seismic or static? A very large collection of papers on landslides can be found through Geoengineer.org's online library here:

Good luck!

Hello stresha, may be my answer will help you:

You need to check (gain information by sampling or field tests) the liquidity/consistency index IL/Ic of the clayey soils in situ. This practice is commonly used in Japan.

Hello Rajyaswori Shrestha, may be my answer will help you:

You need:

1. To check (gain information by sampling or field tests) the liquidity/consistency index IL/Ic of the clayey soil layers in situ.

2. By making calculations (slope stability), define the maximum allowable IL (or minimum Ic), when the slope failure will occur (approximate values).

3. IL/Ic can change in time (seasonal changes), therefore You need to obtain the seasonal IL range also (or take the samples in most wet season).

4. Normally when you do monitoring of situation, You can do it by CPT field tests, if you have good qc -> corellations.

This practice is commonly used in Japan.

This is a big practical work actually. But not the most complex, fortunately.

Regards,

Roman

This is my advice.

1. Field investigation

2. Characterization of the materials

3. Create a geological model.

4. Use some of the geotechnical models for estimating a factor of safety.

Dear Jose, Your answer is not an answer at all, as it does not contain any specific information.

Dear Roman, I do not intend to create a debate about how to answer a question but I think that my answer is as specific as required by the question.

Sorry Jose, may be You know too much to give a simple answer. Honestly i`m not familiar with slopes too much.

But as some information stil is in my mind, i think it is better to share it, rather than forget. Maybe someone can use it. Without any intention for any feedback - just for normal conversation. As You might notice, the biggest problem in geotechnical professional socium is the lack of information exchange. That`s due to hard concurrence, of course.

The funniest thing is that there is not too much to know - it is not as hard as chemistry of fundamental physics. But the usefull information is very expensive, a little amount of clean tests and clear data exists, too little people wants to share e.t.c.

It is not a normal situation, if we speak about any move forward, don't You think so? 

Here, at mygeoworld, we are free of competition in market sense (i hope), and can conversate as colleagues with each other (the thing that I cannot afford to myself in my home country, for example).

I kindly ask You to be specific, even if the question formulation is not the best. Please, do not answer on this post.

Dear Madam,

Use some advanced soft-computing techniques with available geotechnical data and field monitoring data so that we can Pre-Warn the failure at some extent.
