依据邯郸地区地质构造及20多年的观测资料,系统研究了地下水位、地壳形变的正常与异常动态变化及其相互关系。本区地形变的主控因素是西部太行山隆起和东部华北平原大幅度沉降的继承性运动,造成地形变向东南方向倾斜;在大区域的周期性强降水后由于地质构造因素地形变向西北向倾斜,形成水位和形变的正常动态变化。采用有效的定量方法提取异常,显示一部分反向西北倾斜的异常与华北的中强震有较好的对应关系。故强降水引起的地倾斜变化不应看作干扰,而是一种引起地壳变形地震前兆的外动力因素,应予高度关注。
Based on the geological structure in Handan and the observation data for more than 20 years, the normal and anomalous dynamic changes of groundwater level and crustal deformation and their correlations are systematically studied. The main controlling factor of the terrain deformation in this area is the inherited movement of the Taihangshan uplift in the west and the subduction of the eastern North China Plain, which causes the terrain to turn to the southeast. After the periodic heavy precipitation in the large area, Tilt to form the normal dynamic changes in water level and deformation. Using an effective quantitative method to extract anomalies, it is shown that there is a good correspondence between some anomalies of reverse NWP and moderate-strong earthquakes in North China. Therefore, the change of slope due to heavy precipitation should not be regarded as interference, but an external dynamic factor that causes the earthquake precursors of crustal deformation. Therefore, it should pay close attention to it.
