摘　　要：利用自主研发的激光干涉绝对重力仪对广州海洋地质调查局海洋地质码头的三个重力基点进行绝对重力测量。通过对测量结果的分析处理和筛选,确定了各个基点的绝对重力值。测量结果表明,该方法具有快捷、高效和测量精度高的显著优势,是一次非常有意义的技术方法探索。可认为通过进一步的技术性能完善和方法改进,绝对重力测量技术将成为海洋重力测量中一种常规的基点测量手段。Absolute gravity measurement of the three gravity base points in the marine geology pier of Guangzhou Marine Geological Survey is carried out,using independent designed laser interference absolute gravimeter.And the absolute gravity values of these base points are determined by filtering, processing and analyzing the survey data.Though the result doesn’ t match up to that of the previous triplicate small cycle combination measurement, it is affected by many factors.This method has some obvious advantages such as rapidness, efficiency and high precision and it is a significant technical probe.If the technical specifications of the absolute gravimeter and the measurement method can all be further improved, the absolute gravity measurement will become a routine method of combination measurement of base points in marine gravity survey.
