Temp. Sheet piling retention system - deadman design

[Bridgegirl67]

I am working on a Temporary sheet piling retention system (TSRS) for staged construction and have reached the deadman design. This particular system needs a tie-back.
My question is:
Is there any reference or guide that assists in this design in regards to the minimum requirements? I am not finding much and in turn am left to assume that the deadman will be the same width and height as the TSRS.
Any advice would be truly appreciated.

Thank You in advance!

Try looking in Pile Buck's Sheet Pile Design Manual for information on deadman design. The active failure plane behind the wall should not intersect the passive failure plane in front of the deadman. If they do intersect, you will have reduced deadman capacity or, even worse, possibly a global stability problem.

A deadman can be made from many things, such as sheet piling, concrete, a horizontal steel of wood beam, etc.

Go to slideruleera.net website sheet piling and H-piles. There is a document US Steel Steel Sheet Piling Design Manual
That will explain design of dead men. It is very similar to the old pile buck mannual

Actually, the Pile Buck Sheet Pile Design Manuals are newer, expanded versions of the US Steel Sheet Pile Design Manual.

Are the Pile Buck manuals (including the older one) available online?

Yes, for sale.

Pile Buck is necessary if you are going to be doing this type of work. Also, I used the Caltrans "Trenching and Shoring Manual" for most shoring design, and it was acceptable, even the standard, in most of the western states. It is downloadable in pdf off their website.

FHWA also has a detailed three volume set "Lateral Support Systems and Underpinning" that can be download in pdf off of their website dealing with temporary shoring. You should also have this.

As a word of advice (I did this type of work for years): It's not really something you should be doing, just because you can and have a license. It's a specialty field and you're going to spend a lot more time on it and likely come up with a lesser design than the folks that do it every day, and are turning out several excavation plans a week year after year.

But then again, if you're the person/firm the contractor wants it's his call and I hope you make a good profit. Just glad I'm not dealing with the deadlines, the contractors, the heartburn, and the DOT inspectors (half of which couldn't speak English well enough to understand, who hires these people?). The upside is it's all temporary, so now there is no liability, it's all done and never going to come back and bite me, unlike the permanent structures.

Thinking of some of the plan review I've done the past few years I've seen some shoddy shoring plans, and the work isn't being done by specialists like I had mis-assumed when I worked in the field.
