I'm a geotech based in Melb
I would say that the damage is due to reactive clay movement, which the Newer Volcanics is famous for.
Although these types of clays do reduce in shear strength when they wet up are cannot see it leading bearing capacity failure / excessive settlement, particularly...
bit off topic, but i have an additional question or 2 regarding rate of gypsum solubility
Does anyone have some experience in rate of disolution for shafts / tunnels etc in gypsum and gypsum bearing weak rock? Is it possible for disolution to occur (or rapidly worsen) within say the period of...
f-d
just to jump in on this thread and get some advice on something you touched on.
You mentioned that you generally use elastic parameters for footing settlements rather than Cr values from oedometer testing. Can I get some clarification on this for own edification:
1. Can I assume that you...
Thanks for all the posts so far, they have been most helpful.
The soil is a residual clay of basalt origin. The liquid limit of this clay is typically around 80-100% and field moisture content is around 40-50%. Plots a CH to MH clay/silt around the atterberg A line.
The clay is considered to...
thanks fot that.
Its basically where I am at at present, calculating the settlement using the consolidation ratio from oedometer testing and applied tank load (ignoring any soil removal from cutting).
I figuring that the excavated soil surcharge that was removed is only good for adding to...
Hoping someone will be able to help me clarify some soil behavoir.
I have a green field site to be developed with a treatment plant which includes tank structures up to ~70m in diameter and approx 5-7m high.
There is a site cut to create a level bench for construction of the tanks, which will...
