在所有自然灾害中，边坡失稳最适合采取避免、预防或纠正措施。地形中固有的成因相对来说已被较好地理解，因此有可能从区域分区的角度来减轻滑坡灾害。本出版物给出了滑坡的定义和原理，并确定了成因条件和过程（固有或基本条件、地质、地貌、水文条件和气候、植被、改变应力条件和材料强度的因素）。描述了调查规划，包括初步研究、识别不稳定和潜在不稳定区域的技术，例如遥感和地面研究，以及单个因素图。对于数据分析，主要概述了制图方法、影响因素的数值评级以及数值 - 制图方法。提到了一些政府和私人对边坡稳定性危害的应对措施。报告结尾总结了操作规则。（英国运输与道路研究实验室）
Of all natural hazards, slope failures are the most amenable to measures directed towards avoidance, prevention or correction. The causes inherent in the terrain are relatively well understood, hence the possibility of approaching landslide hazard mitigation from an areal zonal point of view. This publication gives the definitions and principles of landslides, and identifies causative conditions and processes (inherent or basic conditions, geology, geomorphology, hydrologic conditions and climate, vegetation, factors that change stress conditions and strength of materials). Investigation planning is described, including preliminary studies, techniques for identifying unstable and potentially unstable areas, e.g., remote sensing and ground studies, and individual factor maps. For the analysis of data, primarily cartographical methods, numerical rating of contributing factors and numerical-cartographical methods are outlined. Mention is made of some governmental and private responses to slope stability hazards. A summary of operational precepts closes the report. (TRRL)
