高密度电法评价岩溶地下水分布

2D Resistivity Imaging Surveys Used to Evaluate the Distribution of Groundwater in the Karst Area

本文利用高密度电法对第四系土层进行了勘查,利用所得到的高密度电阻率反演剖面资料,进行了分析、切片,形成等深度的高密度电阻率勘查反演电阻率平面分布,推断地下水的空间活动规律。对利用高密度电阻率勘查推断地下水的空间活动规律进行了一次有益的尝试,为进一步认识地面塌陷和预防治理提供科学依据。

As one method of geophysical survey, 2D resistivity imaging surveys has been fully used in geologicaldisaster and engineering investigation. The overlying Quaternary soil was surveyed by 2D resistivity imaging surveys, and 2D resistivity inversion profiles were obtained from the survey. Based on analysis of the inversion profiles, we can infer the law of space activities of groundwater. This is a useful attempt to infer the law of space activities of groundwater by 2D resistivity imaging surveys, which would provide a scientific basis to further prevent or treat the ground subsidence.
