OSTI ID:6509946
Results of a microgravity survey at Wilson Dam Power Plant Switchyard, Florence, Alabama, are presented. The survey consisted of 288 gravity stations, with approximately 25% of the stations reoccupied during the survey. Objectives of the survey were to detect any anomalous zones in the switchyard foundation which might be indicative of shallow cavities. At least 75% of the downstream switchyard area has no significant gravity anomalies. In the remaining area, several gravity anomalies are identified which could be indicative of subsurface cavities. If the anomalies are due to cavities, the probable depth range is 5 to 18 ft to the center of the feature. Most of the switchyard structures are in the area free from significant anomalies.
