SAND LIQUEFACTION

LICUACION DE ARENAS

THE PROBLEM OF SAND LIQUEFACTION BECOMES APPARENT THROUGH VARIOUS EXAMPLES WHERE SEVERE DAMAGE OCCURRED. THE MOST IMPORTANT FACTORS WHICH HAVE AN INFLUENCE ON THE PHENOMENON ARE: A) TYPE OF GROUND; B) RELATIVE COMPACTNESS OF THE GRAIN C) INITIAL CONFINING PRESSURE; D) VALUE OF REPETITIVE LOADING; AND E) NUMBER OF LOAD CYCLES. TO STUDY THIS PROBLEM IN THE LABORATORY, TRIAXIAL TEST APPARATUS ARE USED WHERE THE DEVIATOR OF VERTICAL STRESSES MAY BE VARIED IN CYCLES. SIMPLE SHEAR BOXES ARE ALSO USED, IN WHICH THE DIRECTION OF HORIZONTAL DEFORMATION IS INVERTED AND VIBRATION IS APPLIED WITH CONTROLLED ACCELERATION. A SIMPLE SHEAR APPARATUS IS DESCRIBED (AL-72), WITH WHICH THE EFFECT OF THE VERTICAL PRESSURE ON THE INERTIA FORCES MAY BY STUDIED, THE TANGENTIAL DEFORMATION IS CONTROLLED, AND THE SAND SAMPLES (30X60X90 CM) MAY BE PHOTOGRAPHED THROUGH TRANSPARENT WINDOWS. THE METHOD OF PREPARING HOMOGENEOUS SAMPLES IS DESCRIBED.
