摘要

对三原井水位值与口镇-关山断裂带上的垂直形变值进行相关分析,结果显示,二者存在一定的相关性。说明三原井水位变化一定程度上反映了口镇-关山断裂的活动;通过相关资料的对比分析,认为该井上游的冯村水库蓄水量受降雨季节的影响很大,较短时间内可能对三原井水位的异常上升有一定影响;但断层活动是导致三原井水位变化的直接因素。同时讨论了水位异常与地震活动的关系。
Through the correlation analysis between the water level at Sanyuan deep well, after removing the effects of pressure and solid tide, and the vertical deformation in Kouzhen-Guanshan fault, it is found that there is some correlation relationship between them. We can get the conclusion that the water level change reflects the faulting activity around the well to a certain extent. Through the contrast analysis of correlation data, we found that although the water lever of Fengcun reservoir, which is on the upriver of the well, is controlled by the rainfall and has some short-time influence on the well抯 water level, the fault activity is a direct factor for the water level variation in the Suanyuan well. The relationship between the water level abnormity and the seismic activity is also discussed.
