软硬互层岩质高边坡切层滑坡演化机制研究

Research on the Evolution Mechanism of Layer-Cutting Landslides in High Rock Slopes with Soft-Hard Interlayered

摘要: 软硬互层岩质高边坡是指由交替分布的软层和硬层岩石构成的高边坡，这种岩层交替的结构使得边坡在受力时，软层和硬层之间的强度差异较大，导致在特定条件下，软层容易发生滑移，而硬层则相对稳定。此类滑坡灾变在山区、交通基础设施及水利工程周围频繁发生，给人类生活及财产安全带来了严重威胁。随着我国高速公路、铁路建设及水利水电工程的不断推进，软硬互层岩质高边坡的稳定性问题日益受到重视。本文基于软硬互层岩质高边坡的特点，研究了切层滑坡的灾变演化机制，探讨了其发生的内在机理及影响因素，并提出了防治措施，为相关领域的工程实践提供理论依据。

Abstract: The soft-hard interlayered high rock slopes refer to high slopes composed of alternating layers of soft and hard rocks. This alternating structure results in significant strength differences between the soft and hard layers when subjected to stress, leading to the potential for sliding in the softer layers under specific conditions, while the harder layers remain relatively stable. Such landslide disasters frequently occur in mountainous regions, around transportation infrastructure, and near hydraulic engineering projects, posing serious threats to human life and property safety. With the continuous advancement of highway, railway construction, and water conservancy hydropower projects in our country, the stability issues concerning soft-hard interlayered rock high slopes have garnered increasing attention. Based on the characteristics of these slopes, this paper investigates the disaster evolution mechanisms associated with layer-cutting landslides. It explores their intrinsic mechanisms and influencing factors while proposing preventive measures aimed at providing a theoretical basis for engineering practices in related fields.
