高密度电阻率法及地震反射共偏移法在九华山滑坡体探查中的应用

地球物理探测方法在滑坡地质灾害探查中具有简单快捷的特点,可查明滑坡的地质信息,如滑坡体的厚度、规模及发育特征等重要信息,进而进行钻孔布置,获取滑坡体稳定性计算所必须的物理力学参数。在九华山滑坡体采用地震反射共偏移技术及高密度电阻率法对滑坡体进行联合探查,两种方法相互验证,减少多解性,效果明显,获取的相关地质参数为滑坡的评估及治理提供了依据。

The application of the multi-electrode resistivity method and reflection seismic method to the landslide detection in the Jiuhua Mountain

With the charaCTeristics of simplicity and quickness, multi?electrode resistivity method can find out the important landslide geological information such as the thickness, the range and the developmental characteristics of the landslide body in landslide geolog?ical hazards exploration;and then, through drill hole deployment, the physical?mechanical parameters which are indispensable to work out the stability calculation can be obtained. The testing results indicate that multi?electrode resistivity technology performs well in the exploration of landslide body, the result is the same as the reflection seismic total deviation detection technology, and the relevant geo?logical parameters acquired can provide a basis for the evaluation and control of landslide.
