Abstract: Comprehensive experimental results of 54 free‐vibration tests on model footings embedded at various depths in sand and having circular, square, and rectangular base shapes were reported by Erden and Stokoe in 1974 and ...

Abstract: The spectral analysis of surface waves (SASW) method is a nonintrusive testing technique for determining shear wave velocity (

Abstract: A simplified procedure using shear-wave velocity measurements for evaluating the liquefaction resistance of soils is presented. The procedure was developed in cooperation with industry, researchers, and practitioners and ...

Abstract: Results of twenty‐one free vibration tests on surface model footings on moist sand having different base shapes and about equal base area have been reported by Stokoe and Erden (5,8). These tests are used here to verify ...

Abstract: The responses of typical flexible and rigid pavements to the dynamic loads imposed by the rolling dynamic deflectometer (RDD) were investigated. The RDD is a recently developed nondestructive testing vehicle that applies ...

Abstract: To overcome current limitations in predicting in situ pore-pressure generation, a new field testing technique is used to measure directly the coupled, local response between the induced shear strains and the generated ...

Abstract: The nonlinear dynamic properties of highly organic soils from two levee sites in the Sacramento-San Joaquin Delta in California are described. Cyclic triaxial, resonant column and torsional shear tests were performed on ...

Abstract: In situ evaluation of the response of seafloor sediments to passive dynamic loads, as well as spectral analyses of earthquakes are presented in this investigation. The overall goal of this ...
