We are looking for software that is available to design a shotcrete retaining wall with tie backs. We have a project that may require soil nailing to stabilize an excavation below an existing building structure. Thank you for your time and consideration.
 

RE: design of shotcrete retaining wall with tie backs

The soil nailing is the mechanism by which your retained face is held up.  Generally, whatever you put on the face of the nailed  slope is there to prevent weathering of the exposed face and does not provide too much in the way of support.  The shotcrete may offer structural support but only if it contains steel reinforcement.

You may need to contact a soil nailing company as they do tend to keep their design in-house and I would be surprised if you come across any design software on the market for such a specialised process.  

If you are in the UK or if British Standards are acceptable on your contract, then you can design your soil nails in accordance with BS8006:1995 which approaches the design as a limit state philosophy.

A report has been written in Ground Engineering magazine July/August 1996 on the meeting held at the Institution of Civil Engineers, London on 10 April 1996 which may offer you some guidance.

Hold what I said above!!

I have just come across a paper written by Jim Martin of Kvaerner Cementation in the UK, who has carried out nail design using software called SNAIL.  This is a program developed by CalTrans (California Dept Of Transportation Division Of New Technology, Material & Research, - Office Of Geotechnical Engineering).

Hope this helps

Thank you for your response. We have concluded that we will not find any readily available software, and designed the system by hand. It was just as quick, I think.
