Reese - Wang Vs Broms Methods
Reese - Wang Vs Broms Methods
(OP)
Which is more commonly used?
Also I'm trying to understand the main concepts behind the two.
Broms: Use Rankine passive pressure with an increased 'effective' pile width. This method is used in California Trenching and Shoring Manual I believe.
Reese-Wang: Evaluate different failure states to find an ultimate 'passive failure wedge'. I am not very familiar with the equations or where they are used. Any ideas where I can look?
Is there a good reference besides Geotech Circular No 4 for Reese-Wang equations for developing passive pressure.
Thanks!

RE: Reese - Wang Vs Broms Methods
Based on your post, I assume that this is for a shoring wall of some sort. If so, I would use LPile or similar software to determine the load/resistance/deflection of the soldier piles.
If using passive pressure for soldier piles (which I don't recommend) I would use twice the width of the pile or shaft as the effective width of the passive pressure block and use a hefty factor of safety. It takes a lot of deflection to mobilize passive pressure.
