本研究提供了影响不丹东部喜马拉雅山脉主要东西运输走廊的滑坡数据，靠近主要中央冲断层。本研究的重点是提取结构和几何信息的地面激光扫描（TLS）数据利用案例研究滑坡，南林滑坡。TLS数据的分析允许提取的滑动几何形状，不连续的方向和识别的故障模式。TLS的结果相比，传统的工程地质调查，并证明产生相当大的附加值，并应形成新的方法地貌研究和现场评估的基础。宏观尺度的地貌勘察结果概述和解释内的概念模型的滑坡特征的演变，这里称为层次滑坡。结论是南岭山泥倾泻是深层次变形的指示，而不是纯粹的道路建设的功能。
This study presents data on landslides affecting the main west–east transport corridor in the Himalaya of eastern Bhutan close to the Main Central Thrust. The study focuses on the extraction of structural and geometrical information from Terrestrial Laser Scanning (TLS) data utilising a case study landslide, the Namling Landslide. Analyses of the TLS data allow extraction of slide geometry, discontinuity orientations and identification of the mode of failure. The TLS results are compared to a traditional engineering geological survey and prove to yield considerable added value and should form the basis of new approaches to geomorphological studies and site assessment. Macro-scale geomorphological reconnaissance findings are outlined and interpreted within a conceptual model of the evolution of landslide features, here termed hierarchical landsliding. It is concluded that the Nam Ling Landslide is indicative of deeper seated deformation and is not purely a function of road construction.
