DETERMINATION OF THE ELASTIC MODULUS OF SOIL BY THE PRESSURE METER TESTS-THEORETICAL BACKGROUND

A PRESSURE METER IS USED TO DETERMINE THE ELASTIC MODULUS OF A SOIL WITH THE AID OF AN EQUATION, DERIVED FROM THE THEORY OF ELASTICITY, RELATING THE VOLUME CHANGE OF THE MEASURING CELL TO THE PRESSURE ACTING WITHIN IT. A THEORETICAL ANALYSIS OF A DISCREPANCY, FOUND IN THE MEASUREMENTS OF KOMORNIK ET AL, OF ONE-THIRD FROM PREVIOUSLY DETERMINED MODULI VALUES IS PRESENTED, AND IT IS SHOWN THAT THE CONVENTIONAL ELASTIC EQUATION USED IN DETERMINING E APPLIES IN THE CASE OF THE PRESSURE METER, IN SPITE OF THE DISSIMILARITY OF THE RESPECTIVE UNDERLYING CONDITIONS. THE ABOVE DISCREPANCY IS DUE TO THE CROSS-ANISOTROPIC CHARACTER OF THE SANDS IN QUESTION, IN WHICH CASE THE EQUATION IS VALID ONLY FOR THE HORIZONTAL MODULUS; THE VERTICAL MODULUS IS UNOBTAINABLE BY THE PRESSURE METER METHOD. /AUTHOR/
