    黄土地震滑坡研究综述与展望

    A review of earthquake-induced loess landslides research and future prospects

    • 摘要: 黄土地区地貌形态复杂,地震频发,地震滑坡灾害严重。黄土地震滑坡受多种因素影响,包括黄土边坡地形地貌、地层岩性、动力响应,黄土强度和动力特性,水文地质条件等。目前,黄土地震滑坡研究主要采用室内试验、物理与数值模型试验、野外调研、遥感与监测等手段,研究内容包括黄土地震滑坡成因机理、发育特征与分布、滑坡动力响应和稳定性等方面。文中阐述了黄土地震滑坡国内外研究现状,介绍了一种考虑地震波动特性的拟动力评价方法,并对基于拟动力法开展黄土地震滑坡研究进行了展望。通过分析黄土地震滑坡力学成因机制、研究黄土滑坡地震液化现象、讨论黄土地震滑坡失稳特征,提出能够精确评价黄土地震滑坡稳定性的计算方法,可以为黄土地区防震减灾提供理论依据,也是今后研究的重点。

       

      Abstract: The loess region is characterized by complex geomorphological patterns. This region is prone to frequent earthquakes with serious seismic landslide disasters. Loess seismic landslides are affected by a variety of factors, including the topography and geomorphology of loess slopes, stratigraphic lithology, dynamic responses, strength and dynamic characteristics of loess, and hydrogeological conditions. Current research on loess seismic landslides primarily involves laboratory experiments, physical and numerical simulations, field investigations, and remote sensing and monitoring techniques. The research focuses on the mechanisms, development characteristics, distribution, dynamic responses, and stability of loess seismic landslides. This paper reviews the current state of both domestic and international research on loess seismic landslides, introduces the pseudo-dynamic method that considers seismic wave propagation characteristics, and outlines future research prospects based on this method. By analyzing the mechanics mechanisms of loess seismic landslide, investigating the seismic liquefaction phenomena of loess landslides, and discussing the instability characteristics of these landslides, this study proposes a calculation method to accurately evaluate the stability of loess seismic landslides. This research can provide a theoretical basis for earthquake disaster prevention and mitigation in loess areas, and it represents a key focus for future studies.
