Stabilisation of alluvial clay
Stabilisation of alluvial clay
(OP)
I wonder if any other members can offer advice?
I am seeking an economic method of increasing the shear strength of alluvial clay before constructing a platform.
Due to the location of the site (Adjacent to a railway), I would rather not go down the temporary works path and infill new engineering material to a suitable depth, thus methods I have considered are Jet Grouting, SoilFrac grouting or piling.
The alluvial clay has a depth of 2.5m.
If anyone has any alternative ideas, I'd be grateful for your views!

RE: Stabilisation of alluvial clay
As the proposed foundations for the new platform are only 0.5m away from the rail sleeper ends, I'm very relucant to excavate to this depth for obvious reasons. (Temporary works isn't a popular phrase on the railways!)
The report stated that the soil was weak with a low shear strength and the clay was well above the water table.
I am trying to achieve a shear strength in the soil where-by pad foundations for the new platform can be installed at a relatively shallow depth.
Thanks again.

Of course, you may still have a floor/platform settlement issue...depending on how it is designed and constructed.

This is an 'old' thread; posting to it now doesn't help UKENG7 much, ElGreco - I'll bet that s/he has made a decision and proceeded with the project since the last post before yours was dated April 5, 2004 (roughly 100 days ago.)
Please re-read the thread - and note that we asked for more information, which was not provided. While your answers may have worked on some sites, some of them aren't particularly appropriate next to a working rail line.
