The pressuremeter test is one of the most popular in-situ soil testing methods. Developed in the 1950s in France, the test has evolved throughout the past decades and was built into a cone resulting in a cone pressuremeter device (CPM). A proposed extension of the test involves time dependent pressurisation of the device resulting in wave propagation in the soil. Therefore, the dynamic behaviour can be determined. The possible applications of this extension include the response of an offshore monopole to dynamic loading and liquefaction analysis. The present research work deals with the modelling of the dynamic version of the pressuremeter test. The soil where the test was assumed to be conducted was saturated sand. Therefore, it was modelled as a porous medium, following the poroelastic theory by Biot (1956). The latter was based on the consolidation theory (Biot, 1941).
