Seismic-Wave-Based Testing In Geotechnical Engineering

TLDR

Seismic and other geophysical testing methods are becoming increasingly important in geotechnical engineering due to their strong theoretical foundation, reproducibility in lab and field, and noninvasive nature. The paper reviews the fundamental concepts of seismic wave testing as applied in geotechnical engineering. The authors provide a concise review of the core principles underlying seismic wave testing in geotechnical contexts. Case histories illustrate how seismic wave testing yields engineering design information, highlighting its strengths, limitations, and suggesting future research directions.

Abstract

As the geotechnical engineering profession moves forward into the twenty-first century, the role of seismic testing, as well as other geophysical testing methods, will increase. Geophysical methods present unique advantages, including a strong theoretical basis, the ability to perform the same basic measurement in the laboratory and field, and the noninvasive nature of many of the tests. A brief review of the fundamental concepts of seismic wave testing as applied in geotechnical engineering is presented. Determination of engineering design information (subsurface conditions and design parameters) is illustrated through case histories, which also highlight some of the strengths and inherent limitations of the methods. Suggestions for future directions, applications and potential developments are offered.
