Change in soil strength adjacent to closed end metal shell pile
Change in soil strength adjacent to closed end metal shell pile
(OP)
I have been asked by a client to determine the change in soil strength along a metal shell pile. All the books that I have tell me that in a cohesive soil the strength is reduced during driving and will be regained and increased in some cases say a month after driving. I am being asked to qualify and quantify this. Does anyone know of a text book or other resource I could get my hands on to get more information on this?
Thanks
Thanks

It has been my experience significant strength gain can be experienced in one hour. When it is necessary to stop driving to weld on a new section, it usually is noted even in that short time.
There are some of those persons in this group also so stick around.

As OG noted, ask a few pile driving contractors...in particular ask them for "retap" strength changes. You'll probably get more data from mandrel driven shell piles than closed-end steel pipe.
