IT ALSO CRACKS WALNUTS - A NEW TECHNIQUE FOR SOIL COMPACTION

A NEW TECHNIQUE, CALLED DYNAMIC CONSOLIDATION, FOR SOIL COMPACTION ON DEEP FILL AND POOR SOILS, INVENTED BY TECHNIQUES LOUIS MENARD OF PARIS, IS DESCRIBED. THE SYSTEM CONSISTS OF DROPPING IN FREE FALL A WEIGHT OF 8 TO 20 TONS FROM A HEIGHT VARYING BETWEEN 6 AND 25M ON TO THE GROUND TO BE COMPACTED. THE SHOCK WAVES AND HIGH STRESSES INDUCED IN THE SOIL RESULT IN COMPRESSION OF THE VOIDS AND A PARTIAL LIQUEFACTION OF THE SOIL WITH THE CREATION OF PREFERENTIAL DRAINAGE PATHS THROUGH WHICH PORE WATER CAN BE DISSIPATED, RESULTING IN CONCOLIDATION. DETAILS ARE GIVEN OF PRELIMINARY TESTS WHICH ARE PERFORMED ON SOIL SAMPLES IN THE LABORATORY, AND OF VARIOUS IN-SITU TESTS ON THE SOIL DURING TREATMENT. IN ADDITION, RESULTS OF THE USE OF THE METHOD IN IN CORBY, NORTHAMPTONSHIRE, ARE PRESENTED. /TRRL/
