Hey great reply Panars. I've considered rock anchors and have opted out, so I haven't actually specified them, but I have worked with rock on several occasions (with consultation of a geotech).
Don't get rock and concrete confused. Concrete is an engineered material that has much more...
Let me see now, civil engineers developed the beam on elastic foundation theory back in the railroad days (when civil was king). The theory was extended to cover hooping stresses in pipes etc..
It would seem that your dealing with a beam on elastic foundation, as a pipe and a as a beam...
Standard charts for slender compression members don't exist.
California's population pressure blowing through the Northwest.
That is a funny qote, thanks ACtrafficengr.
Your hydraulics engineer should give you a velocity, typcially via USACE software. I've assumed and analyzed boulder impacts, but avoided giving an answer, too many unknowns and I wouldn't want something documented pinning me down to a specific boulder.
Your geotech should give you values...
I think the following statement is both extremely important and is also extremely profound.
ALL UNITS ARE COMPARISONS AND ARE THEMSELVES DIMENSIONLESS.

Will anyone recommend a basic design software for creating moment and shear envelopes. There are a number of free programs that will analyze continuous beams, but I haven't seen one that will account for support stiffness. Also software that is not flexible in load definition, for instance...
Looks like yakpool is the guru on this one. Have you had any experience with transverse post-tensioning of cast in place decks? or CIP slab bridges (in addition to the main longitudinal prestressing)? I know someones done it, but in my short career I've never seen it. When would it be...
Just found this website. I doesn't have exactly what I wasn't looking for. Nonetheless, it looks like a kick butt website with photos and links take a look.

Before I was an engineer, I remember some blasting for a building. I don't intend on switching geotech firms. And it would seem to me the contractor would be the one to determine the final technique, as long as it meets all the requirements. It sounds like little drilled charges would work...
