Active Anchor Earth Pressure
Active Anchor Earth Pressure
(OP)
Hi All
I currently have a situation where we are building next to a railway with a retaining wall between us (our property on the higher level). They require us to compile a report of what our structural effect/loadings it will add to the retaining wall. I have calculated this according to the relevant surcharges applicable to the area. They will ultimately decide whether or not the retaining wall can accommodate the load.
I just want to get a rough idea of how much of a influence my loadings will have. The retaining wall has active anchors, does this imply the that the passive soil pressure against wall (as it is being "pulled" into the soil) is a function of the tension the cables have in them?
Kind regards

As a minimum foundations need to extend beneath the active soil wedge.
Or if you can review the retaining wall design and prove that the wall still have sufficnet FoS with your additional load. This wouldn't be my choice, I'd pile it

The anchors should not enter into your analysis unless the new, lateral, surcharge pressure(s) exceed the original design pressure. After you provide the new lateral surcharge pressure(s), I assume the railroad will tell you (as you mentioned above) if their wall, including the anchors, is OK.
If prestressed anchors are doing their job, they will be pushing the wall back more than the retained soils and surcharge are pushing the wall forward. If the anchors are not prestressed, they are holding only the load that is actually being applied.
