CHAPTER 3

GEOPHYSICAL SITE EXPLORATION METHODS

3.1Introduction

Geophysical site characterization methods measure the response of soil to mechanical or electromagnetic waves and then correlate those responses to engineering properties. Typically, geophysical methods do not impart large strains to soil and, therefore, are considered nondestructive. The mechanical vibrations produced by some geophysical methods such as the seismic methods induce very low strains on the soil.

Most geophysical methods rely on sharp contrast in physical properties within soil layers. For example, when a relatively soft soil overlies a much stiffer stratum, a significant amount of energy would reflect off the interface back into the softer soil, and a relatively small ...
