摘要
本文对长江三峡及其周缘地区完全布格重力异常和均衡重力异常值精算的方法、精度及其实际结果进行了阐述;分析并探讨了该区重力异常场的基本特征和它们与深部构造环境、地震活动间的关系。
In this paper, the theory, method and accuracy of calculating the complete Bouguer gravity anomaly and the isostatic gravity anomaly in Sandouping Dam area, the Changiang Sanxia gorge and adjacent region are expounded,and the actual calculatical results of the gravity anomaly field in these region are shown.The main properties of gravity anomaly field and the relations between these properties and the depth tectonic environmet and the seismicity are analysed and discussed.
