摘要

不稳定斜坡是一种常见的地质灾害,近年来,我国的不稳定斜坡地质灾害日渐频繁,对人民的生命财产造成了很大威胁。采用瞬变电磁法对某不稳定斜坡进行探测,结合钻孔资料推断了覆盖层厚度、岩石风化和完整程度,查明地面裂缝的分布特征,取得了较好的勘探效果,不仅效率高、成本低,而且结果直观、地质效果明显,为后期治理提供了可靠的地球物理依据。
        Unstable slope is a type of common geological hazards.In recent years,geological hazards on unstable slopes are becoming more and more frequent in China,which poses a great threat to people's lives and property.The transient electromagnetic method obtained good exploration results,which is used to deduce the thickness of overburden,weathering and integrity of rock and find out the distribution characteristics of ground fissures,the anomaly is verified by drilling data. The results are not only high efficiency and low cost,but also intuitive and obvious geological effect.It provides a reliable geophysical basis for later treatment.
