Abstract : The study presents the results of preliminary tests on a three-dimensional soil stress cell. The results indicate that: (1) The hydrostatic response is linear fr stress up to 3000 psi. (2) The cell requires no calibration. (3) Its response is insensitive to variations in soil stiffness. (4) Its dynamic response closely follows the decay of the overpressure pulse. (5) With a few exceptions, the measured stresses computed from the stress cell data and corresponding stresses in the soil are within 10 percent absolute. More extensive testing and evaluation is required before the stress cell developed can be used with complete confidence. (Author)
