Can someone educate me. I presume you are referring to a vibrating wire strain guage? I have never seen these used on a static load test, only a simple dial gauges.
Is there a standard that recommends both or is it just belt and braces approach?
in 55 years the soil should have consolidated, and you will get an increase in undrained shear strength and thus allowable bearing capacity. Difficult to say how much, it can be estimated but does take a bit of work.
How large is this vessel, for most large foundations, bearing capacity is not...
In terms of geotechincal stability, id have to crunch the numbers on it but it looks like it would be fine.
Now there's some structural detailing thats needed, like ensuring the loads from the house are transferred to the new L wall footing.
How is the old wall and new wall attached? they need...
People mainly due CU tests to determine effective stress parameters. This is because a CD takes way too much time and is too expensive. CU with pore pressure measurements should gave the same effective stress parameters as CD tests.
There is no undrained phi angle for cohesive soils. There as...
The A line decides, dont go into looking at make up of clay and silt individually, look at the fines content (i.e. sum of both). For fine grained soils, anything above 50% in US and 35% in UK is a fine grained soil
there can be exceptions but thats a good base to start from
yes, when I say placing the concrete will improve it, I mean that it will be reapplying the pressure that the soil had felt previously (plus a little more maybe). Soil at grade level loosens a little because of the removal of stress.
If you are really concerned, you can also dig a little pot...
The 6inches of soft stuff beneath the beams is a pain in the ass. I would have definitely made them trim it out before concreting. There's nothing you can really do now bar make them break out your foundations but tbh its not worth all that. the upper 0.6inch or so of soil does tend to get a...
there are many different ways of doing it, the old traditional way was just a lumped factor of safety of 3 on your combined shaft and end bearing capacity.
but read any text book on geotechnical or foundation engineering. 30 seconds of google and you would have got your answer
