| 摘 要： | 以毕(节)威(宁)高速公路某采空塌陷区勘察为例,将高密度电阻率法用于查明采空塌陷区的空间几何形态、岩体完整性及其含水饱和度。通过反演分析,高密度视电阻率等值线图清晰地反映出采空塌陷区的空间几何形态。结合钻孔分层,利用各岩性介质的理论电阻率值与实际视电阻率值之间的差异,初步分析塌陷区内各岩性介质的完整性及含水饱和度。利用钻孔验证,说明高密度电阻率法用于查明该采空塌陷区空间几何形态是一种有效的物探方法。

| Abstract: | Taking exploring a subsidence area of the Bijie-Weining freeway for example,the paper argues that the high density resistivity method(HDRM) can explore the spatial geometric forms,rock mass integrity,and water saturation of the subsidence area.The HDRM's inversion isogram can clearly image the geometry of the subsidence area.And combining the drilling layering,the paper simply analyzed the massif completeness and water saturation of the subsidence area,through every massif's differences between the true res... |
