1.3 Earth Pressure Cell Construction

1.3.1 Model 4800 Earth Pressure Cells

Model 4800 Earth Pressure Cells may be rectangular or circular in shape. The standard
size for the rectangular Model 4800 is 150 mm × 250 mm (6" × 10"), for the circular it is
230 mm (9") in diameter. Standard thickness for both styles is 6 mm (aspect ratio ≈ 40).
For laboratory tests, smaller, thinner cells can be manufactured. Contact the factory for
additional information.
