cutting an area out of tunnel floor
cutting an area out of tunnel floor
(OP)
I have a large tunnel that I need to put a spread footing in. The tunnel is 100 years old and the existing floor cannot support the load new column load. I am proposing cutting a section of the floor out to install a new spread footing.
The box section that represents the tunnel obviously has compressive forces acting through the floor ....I am thinking/hoping that those forces redistribute around the new opening and the floor handles those forces like a diaphram.....what kinds of things can I check to make sure this works as planed

I can picture a beam along, and parrellel to, the base of each wall of the tunnel with a compression member at each end. The whole thing lying in a horizontal plane at the base of the wall.
Then cut out the floor between the compression memebers, place the new footings and columns, and repour the floor back in place.
Just a thought.
