摘要
人类活动不断向山区纵深化发展,易引发滑坡、崩塌、泥石流等地质灾害。大型滑坡成因复杂、危害严重,治理难度大,给勘察工作带来巨大挑战。现有滑坡勘察技术手段与体系比较单一且勘察效果不佳,尤其是在大型滑坡滑动面准确位置确定和滑带土钻探工艺等方面,一直是困扰滑坡勘察的难题。本文以下个寮大型深层凝灰岩滑坡体实例,分析了大型深层凝灰岩滑坡勘察的难点,提出了综合勘察新思路,并建立了大型凝灰岩滑坡勘察综合体系,为后期类似大型滑坡勘察提供参考。
With the development of the human activities in mountainous areas,it is very easy to cause landslides,collapses,debris flows and other geological disasters.The large-scale landslide is complex in nature,serious in harm and difficult to control,which brings great challenges to the investigation work.The existing survey technology means of landslide are relatively single,no unified survey system,especially the determination of the exact position of the sliding surface and the adoption of the technology by the slide belt soil drill,which has always been a big problem for the landslide survey.In this paper,the following engineering examples of comprehensive treatment of large-scale deep tuff landslide mass in Xiageliao are given,the difficulties and shortcomings in the investigation of large-scale deep tuff landslide are analyzed,a new idea of comprehensive investigation is put forward,and a comprehensive investigation system of large-scale tuff landslide is established,which provides important reference for similar large-scale landslide investigation in the later stage.
