This code deals with measuring the total pressure in earthfills, dams, embankment as well as pressures on the surface of retaining walls, bridge abutments, etc, by using the technique of balancing the fluid pressure in the cell by a pre-ssure applied to the reverse side of the transducer diaphragm. The same method may also be utilized with slight modification for measuring the magni-tude of stresses on tunnel linings rock and concrete masses and other structures inclusive of hydraulic ones.
