| 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。

| Abstract: | 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. |
