Geo-Trends Review

Hi,

When modeling air packets, you should think about what will happen with these air packets.

1. Are these compressible, but the air cannot flow out? This means with compressing the packets, the stiffness should increase. If the air can flow out (this cannot be simulated in PLAXIS yet), it means that the air packet should have a very small stiffness.
2. Do these air packets add to the shear stiffness? Or are these air packets only loaded under compression? If they are loaded only under compression and the air can flow out, a linear elastic material would suffice. But since bulk modulus and shear modulus are coupled via Hooke's Law in the linear elastic material, this might not give the correct behavior.

Hi,

PLAXIS 3D has nice capabilities to do this. On Bentley Communities you can find the info you need:

• A video how this works: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45897/how-to-model-moving-loads-to-simulate-train-induced-vibrations
• And a case study from the German Highspeed Rail: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45475/3d-modelling-of-train-induced-moving-loads-on-an-embankment

Hello Dr. Aali Pant

You can find several datasets from geoengineering case histories that are freely available through the ISSMGE International Journal of Geoengineering Case Histories.

You can scroll through the previous published issues of the Journal and retrieve the Digital Data associated with each published paper.

Please, make sure to include the appropriate references when using the datasets.

Best Regards,

ISSMGE International Journal of Geoengineering Case Histories

I am a geotechnical engineer in the mining industry and those of us working for mining companies in the United States get information on geotechnical products at conferences. Annual conferences are common with most professional organizations, and l suggest you get in touch with some of these professional organizations to get information on how to market your products. Some of the popular professional organizations/conferences to consider are American Society of Civil Engineers(ASCE), American Rock Mechanics Association (ARMA), Association of Environmental Engineering and Geologists (AEG), and Slope Stability Conference.
