I have to verify the safety of an old construction.
The construction is a tunnel above an L-Wall. The Tunnel is 4,5 above a 3 meter thick concrete slab of the L-wall.
The 4,5 meter of space is filled with soilcement (sand + cement).
I can't find any good value for the modulus of subgrade reaction for this layer.
I can only find the values for it for road construction, which stops at 150 MN/m²; but they are only up to 30 cm thick.
Does anyone know a source where i can find the modulus of subgrade reaction for very thick layers of soil cement?
