Does anyone have a graph or data showing a typical OCR vs Depth for Chicago Clays or Great Lakes clays? I need to estimate OCR values to check settlement for a conduit under a proposed embankment.

I have a 3'10" diamater secant pile with a W27x84 soldier pile spaced everyother pile (6.25'). The compressive strength of the concrete is 4 ksi.How can I determine the composite bending capacity of the the secant pile? I am currently exceeding the bending moment of the wide flange and need to...

Im having trouble finding a photo of an excavation base failure in clay (basal heave). Preferrably, one that shows failure of a braced steel sheetpile SOE system.Anyone have any pictures of one?

I have an 84 inch diam. conveyance pipe going into a 4 foot wide tank slurry wall that I need to design a restraint system for. The pipe has a calculated 145 kip thrust that needs to be balanced by the slurry wall. I am looking for some design examples of how to do this. Any help would be great.

I have a 84 inch diam. conveyance pipe that will be going through a slurry wall. The pipe is putting a force of 145 kips on the wall. I need to come up with a design that will distribute this load. The force must be disperesed through the wall since the pipe is conecting to some flexible piping.

Im working on modeling the forces and yield stress of the pipe in Phase2 by rocscience. It looks like the pipe wont need to be that thick to carry the load. The two wooden piles are 8 feet long into the sketchy that I drew. Its what the client wants to go with.

Its a conveyance pipe for a CSO project.

Yes you are correct. The pipe extends beyond the length of the box culvert. Here is a sketch http://i56.tinypic.com/11tn6mg.jpg From surface to bottom of pipe is 20 feet, top 4 is OH @ 110 PCF , bottom 16 is SW/ML/PT @ 115 PCF. I assumed culvert was filled with water.

I have a horizontal steel pipe burried underneath a box culvert with two wood piles resting between the box culvert and the 60" dia. steel pipe. I have computed the loads and determined that each pile applies 10.6 kips on the pipe. The two piles are spaced 14 ft c/c and I am assuming that the...
