Abstract:

This report describes an attempt to develop a procedure for dynamic calibration of free-filled soil stresses gages embedded in a soil sample. The method presented utilizes a drop-type impact testing machine and a small, instrumented container of soil. The velocity history of a shock pulse applied to the soil sample is measured and the applied stress computed this value is then compared with data obtained from stress gages embedded in the soil. The results showed that the procedure is adequate for unfrozen soil, but for frozen soil the accuracy in the measurement of compressional wave velocity needs to be increased to obtain useful results.
