长江葛洲坝库区及其邻近蓄水前后地面形变特征的初步研究.
PRELIMINARY STUDY ON SURFACE DEFORMATION IN THE CHANGJIANG GEZHOU DAM RESERVOIR AREA AND ITS VICINITY BEFORE AND AFTER RETAINING OF WATER
-
摘要: 本文运用水平和垂直形变观测资料,分析这一地区蓄水前后形变分布特征,指出,虽蓄水时间不久,但存在着较为明显的形变.表明蓄水后库区有下沉趋势,位移矢量指向库区.这些资料对研究和判断今后库区诱发地震的趋势可能有所帮助.Abstract: Based on the observation data of vertical and horizontal deformation, this paper analyses the characteristics of surface deformation in the area before and after the retaining of water and points out that though the time duration after retaining of water is not long, yet surface deformation can be clearly observed. It shows that the reservoir area tends to subside and the displacement vector is directed toward the reservoir area. The data might be helpful in studying and estimating the trend of induced earth-quakes in reservoir area,
