DEVELOPMENT OF AN APPARATUS FOR THE DYNAMIC DIRECT SHEAR TESTING OF SOILS,

Abstract

Effort was made to design and develop a pneumatic direct shear device which can force soil failures on a chosen plane by either dynamic or static loadings. Discussed in detail are the establishment of design criteria, design, construction, and operation of the device, as well as the instrumentation used to control, and record the soil loading phenomena. The apparatus, Dachshund I, can produce spearate of synchronous normal and shear loads up to 500 lb and can accommodate specimens up to 4 in. in diameter and 0.75 in. thick. Time interval for the strain loadings can be varied from 1.0 millisecond to days. The present facility is operable and an extensive soil testing program is currently being undertaken. (Author)
