A FURTHER INVESTIGATION OF A METHOD OF TEMPORARILY ANCHORING A CABLE IN A BOREHOLE

A CABLE MAY BE ANCHORED IN A BOREHOLE BY PACKING THE ANNULAR SPACE BETWEEN THE CABLE AND HOLE WITH A GRANULAR MATERIAL SUCH AS SAND. THE RESULTS OF A PRELIMINARY EXPERIMENTAL AND THEORETICAL INVESTIGATION INTO THE SYSTEM WERE PRESENTED TO THE 1ST CONGRESS IN LISBON IN 1966. TESTS HAVE BEEN MADE ON A MODEL SYSTEM WITH A CAPACITY OF 90 TONS AND ON SEVERAL SMALLER MODELS. THE INFLUENCE OF GRAIN SIZE, MOISTURE CONTENT, AND COMPACTION OF THE SAND AND THE SHAPE OF ANCHOR CABLE TERMINATION HAVE BEEN EXAMINED. A FURTHER SERIES OF TESTS ON THE LARGE MODEL GIVE VALUES FOR THE PRESSURE DISTRIBUTION ON THE BOREHOLE WALL. THESE, TOGETHER WITH THE RESULTS OF NUMERICAL ANALYSES, ENABLE POSSIBLE ANCHORING MECHANISMS TO BE POSTULATED. /AUTHOR/
