Guidelines for Maximum allowed height of temporary shoring with out tie-backs
Guidelines for Maximum allowed height of temporary shoring with out tie-backs
(OP)
Can anybody guide me to "Guidelines for temporary shoring wall" design.
I am trying to find the max allowable height with no tie backs. Also some best practices and design guidelines.
Thanks a bunch

Pile size, pile spacing, active and passive pressures, surcharges, bridging effect reduction, concrete encasement, if any, to name the most relevant...

There are many engineers who will design cantilevered walls up to 20 or more feet high. While you can always find heavy enough and long enough soldier beams or SSP to cantilever this high, the performance may be questionable (too much lateral deflection means too much settlement behind the wall) and the extra steel and installation cost may be more than the cost of lighter, shorter, more closely spaced, soldier beams or SSP with tieback anchors added.

There are lots of other wall options depending on your project requirements. Cut or fill wall? It is a pretty endless subject if you don't provide the specifics for your particular project.

I have succesfully finish couple projects with 6m, 7m, 9m (30 feet?) . Last one was in a hard limestone and pile socket was 9m too. Total displacement of the retaining system was 4cm!
Maybe it is because of different practices in different countries, however, I don't think this is engineering. We have to be bold.

For me, I use cantilever walls when I do not have any other choice or I need a permanent shorinf. I am not such a fan of permanent anchors, I do not trust most of the contractors in this issue. So using cantilever walls for permanent applications makes me feel more confident.
But as you said, cost comparison is another thing.
