ABSTRACT

Two geotechnical applications are used to explore the capabilities of the photographic measurement technique. The first involves a penetrometer freefalling from between 1.2 and 8.0 m into a pot of clay. In this experiment measurement of displacement and acceleration are required for test interpretation, and photography was employed because of practical difficulties in using accelerometers with large fall heights. The second application is looking at the soil displacements and mechanisms during 2-dimensional dynamic compaction tests.
