三号地井水动力学影响因素分析

Analysis of Influence Factors of Well Water Dynamics in No.Three Well

三号地井位于阴山纬向构造带,岱海─黄旗海断陷带是区内的主要活动构造单元,由岱海和黄旗海断陷盆地及其周缘断裂构造组成,对晋冀蒙地区的地震研究有一定的指示意义。通过对三号地井台站、地质构造情况及基础资料的收集整理,并进行了水温梯度实验、气象因素调查、区域地层岩性及地下水运移分析以及取土坑应力卸载模型分析,对三号地井水动力学影响因素进行了分析。研究表明,三号地井2012年以来的快速下降现象受周边环境变迁的可能性较大。

No. three wells is located in Yinshan latitudinal tectonic belt, and Daihai-Huangqihai fault zone is the main active tectonic unit in the area, which has certain significance to earthquake research in Shanxi-HebeiInner Mongolia region. Based on the geological conditions and basic data collection of the No. three well stations,the paper does the temperature gradient experiments, meteorological factors, meteorological factors survey,regional stratigraphic lithology and groundwater movement analysis, stress unloading model of soil pit, and influencing factors of Hydrodynamics. The result shows that the rapid decline of No. three well since 2012 is more likely to be affected by the surrounding environment.
