Walls for Excavation
Walls for Excavation
(OP)
Good day everyone!
We will be rehabilitating an interchange, which includes widening and bridge and roads.
We have a problem wherein the sloping sides of the embankment of an existing elevated bridge approach will be excavated because a road will be constructed beside it (see attached file, the red will the finished grade)
The height of the excavation will be approximately 8 to 10 meters. The existing bridge approach is assumed (most likely) to be from fill materials.
We have researched some methods for retaining it, well, first that came to our mind is sheet pile. But we think that it might be impossible since we cannot anchor it.
We think that we can use bore-pile walls for it. Will it be the best option? If yes, can you give us good reference on the design and construction methodology?
Thanks in advanced!

I have read all your comments, upon discussing this with proper authorities, we opted to use secant pile walls instead. We think it is the best choice.
Do you have links for the typical plans of secant pile walls? Or what should be included in the plans (general notes, typical details, construction sequence)
I already have some of those, just for comparison.
