Abstract

The use of the spectral-analysis-of-surface wave (SASW) method is becoming more common as a tool for integrity testing of lifeline and infrastructure components. The method, which is based upon a fundamentally correct theoretical background, can be utilized at several scales. So far, the method has been used in numerous projects dealing with diverse topics from the integrity of dam foundations, to the soundness of concrete slabs, to the suitability of structural members. In this paper, the efforts by the authors towards developing automated procedures at three different scales are described. First, an automated procedure for reducing data for large scale tests (depth of penetration up to 100 m) is presented. In the second section, a new trailer- mounted device, that in less than 40 sec automatically collects and interprets SASW data, is described. Finally, a new hand-held device, that in less than fifteen seconds, collects, reduces, and archives the results over a distance of 15 cm, is presented.
