Gravity change and its mechanism after the first water impoundment in Three Gorges Project
Gravity change and its mechanism after the first water impoundment in Three Gorges Project
摘要
Abstract
In this paper we have analyzed precise gravity survey and gravity effects resulted from water loading, crustal deformation, ground water level change and precipitation before and after the water impoundment in the Three the most significant, maximum gravity change is 200×10-8 m/s2, but this effect is limited in amplitude and range.Gravity change can be observed about 5 km offshore. The gravity change caused by ground water level change is mum gravity change is near Xiangxi. Monitoring the variation of gravity field and further study should continue in the future.关键词
