• Abstract:
  Florida geology with its non-uniform rock and soil layers, variable deposits of poor soils (clay, organics, etc.), and weathered (and possibly voided) limestone is a major concern for design engineers, contractors, and maintenance personnel. However, determining the makeup and integrity of the underlying soil layering can be challenging. A better and more thorough means of assessing and understanding a larger area of the subsurface at construction sites would help to determine the exact needs of a project or to efficiently maintain existing infrastructure. ; Research Objectives ; Previously, the researchers developed a nondestructive surface test that uses seismic waves to yield useful information about subsurface conditions, showing its effectiveness at identifying and locating voids and anomalies (FDOT project BDK75-977-66). In this project, they further developed the method’s software and tested a field-deployable version.
