低阻沉积岩区地表裂缝识别

Identification of surface cracks in low resistivity sedimentary rocks areas

在工程施工过程中,地表裂缝是比较大的工程安全隐患,而出现在沉积岩区的地表裂缝由于其延伸深度与展布范围的不确定性,其识别就显得尤为重要。本文通过对一实际工作中所遇到的位于低阻沉积岩地区的地表裂缝识别过程的讨论,说明了高密度电阻率法在此类勘探中的优势,并提出了针对性地实施与数据处理建议。

Surface cracks are relatively large potential engineering safety hazards during engineering construction,and the identification of surface cracks appearing in sedimentary rock areas is particularly important due to the uncertainty of their extension depth and distribution range.In this paper,based on the discussion of the identification process of surface cracks in low-resistivity sedimentary rock area encountered in practical work,the advantages of high-density resistivity method in such exploration are illustrated,and targeted implementation and data processing suggestions are put forward.
