Nondestructive Evaluation of Mechanically Stabilized Earth Walls with Frequency-Modulated Continuous-Wave (FM-CW) Radar

Effective techniques for a nondestructive evaluation of mechanically stabilized earth (MSE) walls during normal operation or immediately after an earthquake event are yet to be developed. The main objectives of this project are a) to quantify the laboratory performance and ability of an existing wide-band portable frequency-modulated continuous-wave (FM-CW) radar system for detection of defects behind MSE walls, and b) demonstrate the field applicability and performance of the existing radar system in MSE wall inspections. FM-CW radars offer a significant amount of information about the presence of void location and size behind an MSE wall and other anomalies such as excess moisture and its location.
