The process of gravity piston corer penetrating into sediment was analyzed and the in-fluence factors for this process were comprehensively discussed.The sampler penetration depth theory model was established and the calculation equation of penetration depth was obtained. Based on the ABAQUS finite element software,the sampler penetration process was numerical y analyzed.The theoretical model was verified by the experimental data from 20m-gravity piston sampler deep sea sediment sampling experiments taken by First Institute of Oceanography State Oceanic Administration.Therefore,this paper provides a powerful theory which supports for the further study of abyssal gravity piston sampler.
