A SAMPLE PREPARATION METHOD AND ITS EFFECTS ON SHEAR CHARACTERISTICS OF SATURATED SAND
抄録
A simple preparation method of sand specimen using pluviation apparatus (Conical Hopper Method) by which various desired specimen density can be provided by controlling the filter diameter is developed. It was found that various densities can be achieved by this method without applying vibration or impact. A series of static triaxial compression tests on the specimens preparated by another method (Dry Tapping method) were also performed to compare in detail with the shear characteristics of specimens formed by Conical Hopper method. Tests results showed that shear characteristics due to the effects of difference in sample preparation method can be observed in the triaxial compression tests. It was also seen that Conical Hopper method can provided the uniform and reproducible specimens irrespective of the tester.
