对克孜尔水库跨断层垂直形变近40年的资料和水平形变近32年的资料进行了分析。研究发现,①跨断层形变的变化速率具有明显的不均匀性,根据数据序列走势,变化速率的不同可分为6个阶段;②水库施工对跨断层形变有一定的影响,水库蓄水对跨断层形变有显著的影响;③水库蓄水达到正常库容量后的新平衡状态下,跨断层形变速率变化几乎是无干扰背景下变化速率的2倍;④区域应力场的增强对跨断层形变趋势性转折有显著性影响。 The data of vertical deformation of the Kizil Reservoir over the past 40 years and the data of horizontal deformation over the past 32 years have been analyzed. The results show that: ① The rate of change of cross-fault deformation has obvious heterogeneity. According to the trend of data series, the rate of change can be divided into six stages. ② The reservoir construction has certain influence on the cross-fault deformation. The change of cross-fault deformation rate is nearly twice as much as the rate of change under non-interference background; ④The increase of regional stress field has the effect on the trend of cross-fault deformation Sexual transition has a significant effect.
