高密度电法和天然源面波在渣土场不稳定评价勘查中的应用

Application of high-density electric method and natural source surface wave in unstable evaluation of muck field

近年来,渣土场滑坡地质灾害时有发生,对人民的生命财产造成了很大威胁,因此加强渣土场地质灾害的勘查和防治显得尤为重要。高密度电法和面波法是对渣土场进行探测的有效手段,本文讨论了两种方法相结合在济南市龙洞(R3线停车场)渣土场不稳定评价勘查项目中的应用效果,并结合钻孔资料推断了渣土体形态及埋深,取得了较好的勘探效果,为后期治理提供了可靠的地球物理依据。利用高密度电法和天然源面波法来勘查渣土体不仅效率高、成本低,而且结果直观、地质效果明显,是地质灾害勘察中有效的地球物理勘查技术。

In recent years, landslide geological hazards often occur in muck field, which posed great threats to people’s lives and property. Therefore, it is particularly important to strengthen the exploration and prevention of geological disasters in slag field. High-density electrical method and surface wave method are effective means to detect the slag field. In this paper, the authors discuss the application effect of the two methods combined in the instability evaluation exploration project of the Longdong(Line R3 parking lot) in Jinan City. Combined with the drilling data, the slag body shape and depth are inferred, and a good exploration effect is obtained, which provides a reliable geophysical basis for later treatment. The use of high-density electrical method and natural source surface wave method to survey slag soil is not only efficient, low cost, but also has obvious results and obvious geological effects. It is an effective geophysical exploration technology in geological disaster investigation.
