通过对克孜尔水库跨断层形变特征进行分析,结果显示:①垂直形变每年3～4月、10～11月分别为峰、谷值时间;水平形变每年6～7月、1月分别为峰、谷值时间。②垂直变形的峰—谷时间间隔在1997年之前多为5～8个月,1998年后多为1～3个月;谷—峰值时间间隔在1997年前多为4～7个月,1998年后多在8～11个月。水平形变在1994年之前峰—谷值时间间隔多为6～7个月,1995年后为7～9个月;谷—峰值时间间隔1994年前多为5～6个月,1995年后多为3～5个月。③垂直形变的谷—峰值差在1984年前比较平稳,之后变化较大;1990年之前峰—谷值波动较大,1993年之后明显减小。水平形变的峰—谷值、谷—峰值差在1997年之前变化较大,之后变化明显减小。④水库施工及蓄水初期对跨断层形变有显著影响,尤其对垂直形变的影响特别明显。 Through the analysis of the deformation characteristics of the Kezier Reservoir across the fault, the results show that: ① vertical deformation from March to April every year, from October to November were the peak and valley time; horizontal deformation from June to July each year, January were peaks , Valley time. ② The peak-valley time interval of vertical deformation was mostly 5-8 months before 1997 and 1- 3 months after 1998. The valley-peak time interval was mostly 4-7 months before 1997 After more than 8 to 11 months. Horizontal deformation in 1994 before the peak - valley interval for more than 6 to 7 months, after 1995 for 7 to 9 months; valley - peak time interval of 1994 to more for more than 5 to 6 months after 1995 For 3 to 5 months. ③ The vertical deformation of the valley - peak difference in 1984 before the relatively stable, after a larger change; before 1990 peak - valley fluctuations, significantly reduced after 1993. Horizontal deformation of the peak - valley, valley - peak difference in 1997 before the larger changes, the change was significantly reduced. ④ Reservoir construction and initial storage have a significant impact on the cross-fault deformation, especially on the vertical deformation.
