This article is a review of the work that has been done in a sub-field of soil mechanics, namely stochastic soil dynamics, whereby the ground is viewed as a material whose properties are random functions of space and time. This is a relatively new concept, which first emerged in the early 1960s within the context of acoustic waves in the ocean and electromagnetic waves in the atmosphere. Since then, new fields of application, such as biomechanics, non-destructive testing, aeroelasticity, etc have been found. The present article discusses the aforementioned concept within the framework of the various sub-disciplines of soil mechanics, always emphasizing the predominantly dynamic (i.e. transient) nature of these phenomena. Finally, besides presenting an extensive review of the pertinent literature, we have also included some background material on stochastic soil dynamics plus a few thoughts on future trends in this rather novel field, which has been under development in the last 20 years.
