looking for stiffness data for dry compacted soils
looking for stiffness data for dry compacted soils
(OP)
Hi, I'm looking for data about the mechanical properties of dried, compacted soils. The soils will be in containers under cover.
The containers will be full, and sealed and they will need to support weight.
Will the compacted soils settle considerably or not.
I think it's stiffness I need to consider inorder to stop the containers from buckling and collapsing.
Can anyone help me out. It would be greatly appreciated.Thanks

Is it possible to achieve a load bearing capacity with a worst soil case, with maximum compaction, or does the elasticity of some soils make this imposible?
I will design the composite structure to handle the compaction, without deformation, if I can get some figures to work with.
If the soil is completely dry will the soil compact sufficiently to utilise the strength of the fibres in the composite material to support weight( like a full sand bag)
The machinery to be held up by these balast feet isnt that heavy.

I would love to tell you but I would then have to kill you. Just kidding.
My Brother owns a software, hardware development company which services the mineral exploration sector.
They have some new equiptment which needs to be protected in remote areas, often this equipment will need to be helicoptered in.
It needs to be in a protective box, about 8'x4'x6' high. The roof is their problem, it is also taken in and contains solar power, climate control gear and other stuff, it isn't that heavy but the walls of the box need to hold it up.
It is not always practical to bring in blocks or other conventional building materials.
I thought I could make light weight hollow composite panels and fill them with dirt,from the sites, dried and compacted,to give the thing weight to stop it blowing away ,also to give it impact resistance and insulation both thermal and acoustic.Oh! and weather proof of course.
When you say "wont really compact the soil completely dry" what does that mean?
I dont really care if it doesnt compact, as long as it doesnt change volume too much, after I put it in and compact or vibrate it.
If it is completely dry and it wont compact, will it settle over time and will it compact due to the weight on top of the box?
Will it have a stiffness value and if so what is likely to be. Even if we use the worst case scenario, as we dont know what soil we are going to get.Or is the worst case not stiff enough to help the fibres in the panels take a load.
I would like to discuss this,and other projects with someone outside this forum,I could use a geo guy.I would like to give my business to someone from this forum because I appreciate the way they help each other.There doesn't seem to be any way of contacting people to do so.
Thanks again.

Also, the length of time that the structure is to be in service will make a difference.
I would suggest that you contact a couple of local geotechnical engineers in your area, meet with them and find one person that you can work with. Another idea would be to talk to a local engineering prof. Depending on your time line, this would be a good graduate student project.

I'm done. I will take your advice and contact a local geoTech.
This EngTips Forum is a great idea, I can see why you guys use it.
Thankyou Ron also for your help.
Thanks EngTips.
Bye for now....
