摘要
运用精密数值模拟算法,计算了三峡水库库首区不同蓄水高度的重力效应;对比分析了首次蓄水前后局 部重力监测网观测到的重力异常与模拟计算结果。得出结论:三峡水库蓄水引起的重力效应非常明显,蓄水过程 中的重力异常是多种效应的综合反映,其中蓄水本身的直接重力效应是主要的重力效应。
In this paper, we calculated the gravity effect of water-impoundment in the front area of the Three Gorges reservoir on several different water levels with a high precise numerical simulation and compared the gravity anomaly obtained by numerical simulation with that by measured in a local gravity monitoring net during the first water-impoundment in the Three Gorges.We concluded that the gravity effect during the water-impoundment was obvious and related to several factors,direct gravity effect of the water-impoundment plays a main role.
