海底取样器的理论探讨及参数计算——海底取样技术介绍之五

THEORETIC DISCUSSION AND PARAMETER CALCULATION OF SUBSEA SAMPLER∶THE FIFTH INTRODUCTION OF SUBSEA CORING TECHNOLOGY

阐述了海底取样时岩芯形成的理论过程 ,推导了有关理论计算公式 ,得出了形成“桩效应”的条件 。

This paper describes the theoretic formation process of a core during core boring in subsea and then dedues connected theoretic calculation formulas.Also it presents the condition of forming “stake effection” is reached and the theoretic calculation formulas of hydrostatic pressure and multi parameter of vibratory hammer of the sampler.
