The thirteen papers included in this record were scheduled for presentation at the TRB 75th Annual Meeting in a two-part session titled “Small Magnitude Measurements in Geotechnical Engineering,” organized by Thomas C. Shehan, Northeastern University. Because of limitations imposed by the severe snow storm in Washington, D.C., in January, a number of presenters were unable to attend the sessions. Hence, some of the papers in this record were presented, and others were not. Gookin et al. report on combining results from different sensors appropriate for small- and large- magnitude measurements on the same soil sample to observe response over variable frequencies and wide strain range. Miller et al. describe the development of a device consisting of a special soil chamber and a direct simple shear machine for study of sand behavior at shear strain levels of 0.003 percent and more. Maher et al. compare results obtained using LVDT and proximity sensors to evaluate granular soil resilient modulus. Gupta et al. present resonant column and torsional shear test results on residual soil samples together with observation of lateral deformation from proximity sensors. Raschke et al. report on their investigation of local deformations in granular media using digital image processing and analysis techniques. Romero and Pamukcu describe characterizing properties of geological and residual material by examining wave patterns produced at low strain and low frequency excitation using digital signal processing and artificial neural networks. Dai and Labuz report on acoustic emissions studies of progressive failure of a weak sandstone subjected to plane strain compression. Vitton et al. compare grain-size distributions of finegrained soils determined by hydrometer analysis and X-ray absorption. Puppala et al. introduce a CPT interpretation method for estimating the shear modulus of cemented sand. Caliendo et al. describe details of instrumentation and data acquisition for study of lateral capacity of single and group model piles. A model study of load-displacement response at a shaft-dry sand interface is presented by El Sakawy and Edil. Burns and Mayne report on correlations between shear wave velocity from seismic cone penetration to initial shear modulus and shear strength. Alternative methods of interpretation of time domain reflectometry data for evaluation of in situ volumetric moisture content are compared by Klemunes et al. (Author/publisher)
