Abstract
A METHOD OF ESTABLISHING THE HOLDING CAPACITY OF ROCK ANCHORS IS PROPOSED. THE TECHNIQUE INVOLVES IMPROVED ELECTRONICS TO ESTABLISH UP-HOLD SEISMIC PROFILES. THESE VELOCITIES WOULD PROVIDE A QUANTIFIABLE METHOD OF DESIGNING ANCHORAGES IN COMPLEX STRATIGRAPHIES AND FRACTURED CONDITIONS SUCH AS COMMONLY FOUND IN CABLE LOGGING OPERATIONS. THE SYSTEM, OPERABLE BY A LAY LOGGER, WOULD ALLOW UTILIZATION OF HERETOFORE MARGINAL RESOURCES BY PERMITTING ACCESS TO DIFFICULT TERRAIN.
