• Abstract:
  This manual describes the setup and operation of the. prototype Seismic Refraction Bedrock Analyzer (SRBA) and the analysis of data acquired with the instrument. The SRBA prototype (fig. 1) was constructed at the Bureau of Economic Geology to aid in the estimation of bedrock depths and seismic velocities beneath paved surfaces. It employs a fixed array of ground-motion detectors (geophones) and a movable seismic source to acquire seismic refraction data that can be analyzed to produce two-layer, planar models of seismic velocity changes in the near surface. The instrument was designed and constructed during studies completed for TxDOT to determine whether existing geological data could be used to estimate bedrock depth to allow better analysis of falling-weight deflectometer data (Paine, 1999; Paine and Murphy, 2000).
