本文利用高密度电法连续监测数据,基于统计学方法对潍坊滨海典型海水入侵区地层电阻率随潮汐作用的时空动态变化进行研究,结果表明:在地层沉积均匀的滨海地区,无论单次测量还是重复测量,地层电阻率值只在垂直方向上具有显著差异性。潜水面附近地层电阻率受潮汐影响最为明显,因此,利用高密度电法连续测量的方法分析滨海地区地下水随潮汐作用时空变化的方法是可行的。 In this paper, continuous monitoring of high-density electrical data, based on statistical methods Weifang coastal typical sea-water intrusion zone of the resistivity of the temporal and spatial dynamic changes in tidal effects were studied, the results show that: in the stratigraphic sedimentation of the coastal area, Repeated measurements show that the formation resistivity values ​​differ only significantly in the vertical direction. Therefore, it is feasible to analyze the spatio-temporal changes of groundwater in the coastal area with the tide effect by the method of continuous measurement with high-density electric method.
