Design Loads for Concrete Liners in Shafts
Shaft will be D&B. Finished ID is 28 ft. The potential for 350 psi at the bottom of the shaft is exactly what I am concerned about. If full hydrostatic is actually acting on the concrete lining, then we will need to almost double the thickness of the lining we are carrying through preliminary...- jarhead76

Design Loads for Concrete Liners in Shafts
Thanks miningman, This is a civil engineering project in the NE United States. We haven't started our sub-surface exploration yet, so I don't have detailed geotech info for you. I can say that we expect the shaft to be located in a shale formation and that grouting will be required. Our...- jarhead76

Design Loads for Concrete Liners in Shafts
Hello, I'm looking for references on design loads for concrete liners in deep shafts. We are doing preliminary design for an 800 foot deep shaft. Site sub-surface exploration has not been completed yet. We are considering using a concrete liner as the permanent lining. I'm interested in...- jarhead76
