深层滑坡（DSLs）涉及大规模变形，并可能影响交通基础设施。移动速度一般非常缓慢（每年不到一米），加速期受诸如地下水压力的季节性波动等外部因素控制。根据水文地质条件、坡面几何形状的变化和地质物质的退化情况，加速响应可能随季节而变化。更多的局部滑坡类型与dsl相关并在dsl内发展，如岩崩、倾倒和碎片滑坡。管理与dsl相关的危害首先需要评估地质、水文地质和地质力学过程。这是制定管理策略的起点。本文介绍了位于瑞士汝拉山脉的深层滑坡的特征，Les Buges滑坡，其中铁路线，电力线和具有区域重要性的渡槽穿过滑坡，以及滑坡趾下经常出现的徒步小径。滑坡运动学受边坡的地质和水文地质的支配，可细分为两个主体。随后将讨论此DSL的管理策略。勒布热是一个很好的例子，说明与深层滑坡有关的危害必须首先通过观测方法加以解决。
Deep-seated landslides (DSLs) involve large-scale deformation and likely affect transportation infrastructure. Movement rates are in general very slow (less than a metre per year) with acceleration periods controlled by external factors such as the seasonal fluctuation of groundwater pressure. Acceleration response may change from season to season depending on hydrogeological conditions, changes in slope geometry and degradation of geological materials. More localized landslide types are associated with and develop within DSLs, such as rock falls, topples and debris slides. Management of hazards related to DSLs requires first the assessment of geological, hydrogeological and geomechanical processes. This is the starting point for developing a management strategy. This paper presents the characterization of a deep-seated landslide located in the Swiss Jura Mountains, Les Buges landslide, where a railway line, a power line and an aqueduct of regional importance cross the slide, as well as a highly frequented hiking trail beneath the landslide toe. Slide kinematics is governed by the geology and hydrogeology of the slope, which can be subdivided into two dominant bodies. A management strategy is subsequently discussed for this DSL. Les Buges is a good example illustrating that hazards related to deep-seated landslides must be tackled first of all by means of the observational method.
