    黄土地区地质灾害链研究初探

    PRELIMINARY RESEARCH ON GEOLOGICAL DISASTER CHAINS IN LOESS AREA

    • 摘要: 黄土由于湿陷性、大孔隙、水敏性等特点,导致黄土地区的地质灾害广布,并且各灾种之间表现出明显的链生效应,使得黄土地区地质灾害的成因机理及防治研究愈发复杂。本文通过分析整理黄土地区典型灾害及灾害链事件,归纳了黄土地区灾害的发育现状,详细描述了两条典型的黄土地质灾害链式结构,并以天水大沟滑坡-泥石流灾害为例,阐述了黄土灾害链链生过程中的放大效应。根据黄土灾害研究现状,凝练了黄土灾害链研究中的3个关键问题,针对性地提出各自的研究思路,并指出今后需更加注重黄土灾害链的风险评价及断链措施方面的研究。本文针对黄土地区灾害链研究中若干问题的初步思考,旨在为后续的灾害链研究提供科学建议。

       

      Abstract: Due to the collapsibility, porous and water sensitivity of loess, geological disasters are widely distributed in loess area in northwest of China and show the characteristic of disaster chains. In this paper, several typical geological disasters in loess area are analyzed and the developmental states of geological disasters are concluded. Furthermore, the structures of two typical disaster chains are well described. In the geological disaster chains, the scale amplification is obvious, which is elaborated according to the 7.23 debris flow in Dagou gully in Tianshui City, Gansu Province. According to current research progress in geological disasters, three key issues are concluded and then the research ideas are given respectively. The research on risk assessment and chain scission about disaster chains should pay more attention to the future research. All and all, the preliminary research on geological disaster chains would be provide scientific reference to the future study.
