中文摘要:
      泥石流是北京地区最严重、最具破坏性的地质灾害类型,为了科学防治泥石流,本次采用高密度电阻率法和地质雷达相结合的方法,通过正反演计算和实测剖面的综合解释,基本查明了北京延庆区松散堆积物的厚度,其中井庄乡果树园村泥石流沟域范围内松散堆积物厚度较大,一般40~60 m,自下游向上逐渐变薄,并且浅部存在一层厚度为10~15 m的块石土堆积层;其余地段松散堆积物厚度一般8~10 m,并估算了研究区松散堆积物的方量。这两种方法的综合应用对松散堆积物的划分具有较好的效果,为科学防治泥石流提供了依据。
英文摘要:
      Debris flow is the most serious and destructive type of geological disaster in Beijing. In order to prevent and control debris flow scientifically, the high-density resistivity method and geological radar method are used in this paper. Through the comprehensive interpretation of forward and reverse calculation and measured section, the thickness of loose deposits in Yanqing District of Beijing is basically found out, among which loose deposits are found in the scope of debris flow gully in Guoguohuayuan Village, Jingzhuang township The thickness of the material is relatively large, generally between 40-60m, gradually thinning from the downstream to the upstream, and there is a layer of 10-15m thick block stone soil accumulation layer in the shallow part; the thickness of the loose accumulation material in other sections is generally within 8-10m, and the volume of the loose accumulation material in the study area is estimated. The comprehensive application of these two methods has a good effect on the classification of loose deposits and provides a basis for the scientific prevention and control of debris flow.
