摘要:
在总结皖南地区泥石流主要特征的基础上,重新梳理了沟谷型泥石流调查评价过程中的调查要素和评价因子,提出了沟谷型泥石流调查评价工作方法:对沟谷进行泥石流初步评价,以可搬运物源量和可淤积容量比值系数作为初步评判标准; 以沟谷泥石流集水盆地形态特征、可搬运物源属性分布及储量、堆积区地形等特征作为主要调查内容,对易发性评价因子赋予分值。在此基础上,以皖南小容泥石流地质灾害调查为例,探讨更直观、更科学、更切合实际的沟谷型泥石流地质灾害调查评价工作方法。
Abstract:
On the basis of summarizing the main characteristics of gully debris flow in southern Anhui, the investigation elements and evaluation factors in the process of the investigation and evaluation of gully debris flow in this area were reorganized, and the work method of the investigating and evaluation of gully debris flow was proposed. That is, a preliminary evaluation of debris flow in the valley is carried out in advance, and the preliminary evaluation standard is established based on the ratio coefficient of transportable provenance capacity and siltation capacity. The main investigation contents are the morphological characteristics of catchment basin, the transportable source property distribution and reserve features of transportable provenance, and the topography of accumulation area of gully debris flow, which were taken as susceptibility evaluation factors and scores, were assigned to evaluate the susceptibility of gully debris flow. Taking Xiaorong debris flow as an example, this paper introduces the practical application of debris flow investigation and evaluation methods, in order to show a more intuitive, more scientific and more practical method for investigating and evaluating gully debris flow in southern Anhui.
