Geology: Engineer Ignore It at Your Peril

Abstract

Geology and related earth processes are an inherent part of civil engineering design and construction. This paper examines eight specific examples to illustrate how geologic factors can dominate project behavior. The examples are from a spectrum of environments associated with design and construction of roads and airfields and vary from the apparently obvious to the more subtle. Failure to understand the geologic conditions at a site almost invariably results in unsatisfactory performance. This complex interplay between geology and engineering is at the heart of the geotechnical profession and should be appreciated by all.
