大地水准面起伏对重力归算的影响研究
Research on the Effect of Geoid Undulation on Gravity Reduction
摘要
Abstract
At present,there are two vertical reference systems that are commonly used in gravity correction.Based on this fact,we choose two profiles with large geoid variation and discuss the effect of geoid undulation on gravity reduction.The results show that the profile's span and geoid gradient will influence on the Bouguer gravity anomaly,so when the gravity detection area's geoid undulation has large changes,the influence of the difference between the geoid and the reference ellipsoid on the gravity reduction is more prominent.When we calculate Bouguer gravity anomaly to inversion and interpretation,the effects of geoid undulation must be considered.关键词
