This paper investigates development of a finite element model to analyse PiezoCone Penetration Test (PCPT) in unsaturated porous soil. The study is carried out due to presence of a type of marine soil which contains Gas Hydrate. This componenet which can be found in seabed sediments of the continental shelf, is stable under special conditions of temperature and pressure. By missing this required condition, the existing theories are unable to predict the soil behaviour, so a numerical code called ?-Stock (Gatmiri, 1997) developed to overcome this problem. The behaviour of soil is considered to be nonlinear elastic and the Piezocone penetration has been modeled in two steps. Interaction of different soil phases have been considered completely coupled. Also all mechanical and hydraulic properties of environment are supposed to be temperature dependent. The intial data of this modeling derived from some field observations in Guinea Golf. The results of this numerical model describe the dissipation and mechanical behavior of these gas hydrate bearing marine sediments with an acceptable accuracy and can be improved in the case of having access to sufficient field observations.
