A SAMPLE PREPARATION METHOD AND ITS EFFECT ON STATIC AND CYCLIC DEFORMATION-STRENGTH PROPERTIES OF SAND

A simple preparation method of sand specimen using multiple sieving pluviation apparatus (msp method) by which various desired specimen density can be provided exclusively by controlling the rate of sand discharge is developed. In the granular materials having a relatively small uniformity coefficient, it was found that the very high density can be achieved by this method without applying vibration or impact. A series of static triaxial compression and extension tests and liquefaction tests on the specimens prepared by different methods were also performed to compare in detail with the static and cyclic deformation-strength characteristics of specimens formed by msp methods. Test results showed that the variation in dilatancy characteristics due to the effect of difference in sample preparation methods can be observed more clearly in the triaxial extension test than in the triaxial compression test and that the lowest cyclic undrained triaxial strength value of msp specimen can be explained by its anisotropic fabric. It was also seen that msp method can provide the uniform and reproducible specimens irrespective of the tester. (Author/TRRL)
