摘　　要：重力活塞取样器是采取海底松散沉积物柱状样品的工具之一,它主要由夹紧机构,释放机构和取样器本体组成。传统设计方法主要是通过经验取值。本文根据理论计算初步预测出在设定的条件下,取样器的贯入深度与配重、沉积物的极限应力摩擦系数、样管周长、最大截面直径、取样器的密度和海水密度的函数关系。并且通过实验数据对获得的函数进行了验证,从而为取样器的设计提供理论指导。Gravity piston sampler is one of the simplest and most convenient coring equipment for getting sediment columnar core samples. It mainly consists of clamping institutions, release mechanism and sampier of ontology. Based on theoretical calculations preliminary forecast, under the set conditions, the penetration depth of the sampler was a function of multiple parameters,including its own mass, the sediment limit stress coefficient of friction, sample tube circumference, the maximum diameter, the density of the sampling device and the density of sea water. And the function obtained was verified by experimental data, so it could provide theoretical guidance for the sampling design.
