How to simulate numerically the collapse of geoetchnical structures?

In a real case story a tunnel collapsed. when simulating the problem by a numerical model using a 3D software Plaxis, at the stage of computation corresponding to the collapse, we noticed large...

Publication's co-authoring Proposals?

We have good experimental results (odometer-shear box and triaxial) related to the behaviour of a variety of reconstituted soil (clay + gravel + sand) to various proportions. The initial objective...

We would like to experiment boundary effects during a direct shear test to investigate the scale effect during shearing.

So we are thinking of designing a "full" scale box (big box) does anyone have an idea about this topic?

Is there any experiences to share related to the compressibility of conglomerates soils?

We are working on the development of a rheological model to fit the observed compressibility (in the standard oedometre) of some variety of artificial reconstituted soils (clays mixed with...

Artificial reconstitutded materials (sand and Kaolin), are they trully representative of the behaviour of some problematic soils (metastables)?

In such soils :the sand simulates the behaviour of the grains in soils, however the kaolin simulates the fine grains (clay) and though the cohesion.

The ultrasound technic is actually used in the prediction of the collapse of some metastases soil. What are the main limitations of this technic.?

Ultrasound could be used for investigating the collapse phenomena of some metastases soils. I am looking for any standardized procedures of testing. thanks.
