Abstract

Abstract

Sampling technology of deep sea sediment is very important for many aspects of ocean researches because the realization amony their research goals is closely related to the quality of sediment samples.While the soft or lightly clotty sediment is sampled with general pipecores,it is always inevitable that sediment samples are disturbed.On the basis of an original equipment witch is named as the manipulat or holding sedimentcorer,a model of sampling process is built and the theory of sampling disturbing is analyzed;the extrusion expansion solution of sediment is gotten through adopting the spherical cavity expansion theory;finally,combining with actual parameters of the Pacific Ocean sediment,a quantitative description on disturbing status of deep sea sediment is presented,and a conclusion that the wall thickness of the core is a key parameter for reducing disturbing is put forward.
