Comprehensive Shear-Wave Velocity Study in the Poplar Bluff Area, Southeast Missouri
The primary objective of this study was to evaluate the utility of the four conventional and/or newly developed methods listed below for determining the shear-wave velocity of soils with a view to estimating frequency-dependent soil motion amplification and/or deamplification. These four methods were evaluated individually and then comparatively in terms of accuracy, functionality, cost-effectiveness and overall utility. the four methods are: crosshole shear-wave velocity, seismic cone penetrometer, multi-channel analysis of surface waves, and ultrasonic pulse velocity laboratory test. in addition, a suite of 3-D maps depicting spatial variations in thickness, stratigraphy, and shear-wave velocity of soils in the Poplar Bluff area was prepared as well as a revised 3-D shallow subsurface materials map complete with shear-wave velocity test data (suitable for preparation of an earthquake soil amplification map). These maps depict the lateral variability of the shallow subsurface materials' shear-wave velocity and stratigraphy, and their range of values or properties.
