Dear Ammar, thanks for your answer.
It is a temporary retaining wall. It is a wall of 200 mm of thickness. I contacted a local installer (soil reinforcement company), and they said they used cables instead of threaded bars (2 strands of 5/8" each, 300 kN, L= 16 m) and the concrete contractor is in charge of the wall construction.
The soil investigation report did not report the phreatic level, and this was a surprise. It was an emergency item for design....
Thanks for your suggestion! I will consider the weep holes. Do you have ny suggestion regarding its location or distribution? The wall is 7 m in height and 40 m long.
Regards,
AG

First step site visual investigation with soil reinforcement company needs to be made. Preliminary layouts to be prepared with required depth and any nearby structures to be shown which may be effected. Soil investigation report to be prepared. Is the reinforcement scope temporary or permanent? Local well established soil reinforcement companies web sites to be visited and companies contacted to submit their bids, method of procedures,etc.? Note for water level presence weep holes are added at one or more levels. For normal soil rock bolts are not used.

Greetings to everyone.
I have some concerns regarding the design of Soil Nail Walls. Do you have an example of calculation (design) of the wall in case of presence of phreatic level? Is it common to use threaded bars instead of cables?
