摘要: 综合物探方法在滑坡等地质灾害的勘探中发挥着重要的技术作用。这里以河南省某地滑坡勘探为例,利用高密度电阻率法和地质雷达法等综合物探方法,分析两种物探方法的技术原理、联合解释,并结合地质钻探、地质调查等资料,查明该场地滑坡体的分布情况。结果表明,综合物探方法能有效地减少物探的多解性,提高成果解释精度,其综合物探解释成果与地质情况较为吻合,显示出综合物探方法在滑坡等地质灾害勘探中的重要作用。最后,对综合物探方法及综合解释进行了简要的总结和展望。Abstract: Integrated geophysical prospecting method plays an important role in the exploration of geological hazards, i.e. landslides. In this study, we apply an integrated geophysical exploration scheme to a landslide in one city, Henan province. We demonstrate the distribution of the ground landslide by combined using data from geological drilling and survey along with an integrated exploration scheme of high-density resistivity method and GPR. And the results indicate that the integrated geophysical prospecting method can effectively reduce the uncertainty of geophysical exploration, and improve the interpretation accuracy. The integrated interpretation is more closely associated with the information from geological surveys, which reveals the significance of the integrated geophysical exploration methods in the research of geologic hazard such as landslide. Finally, we summarize and provide a prospect of the integrated geophysical method, interpretation.
