The Udzungwa scarp is prone to landslide, slope instability, and severe erosion brought about by several interrelated factors like rainfall, soil geological formation, geomorphological feature of the slope and gross engineering properties of the soil available within the scarp. In this paper, some engineering properties of soil available within the scarp are discussed. Various soil engineering characteristics, erosion, and slope stability problems are pinpointed and discussed. This paper is based on the study carried out during pre-construction, construction, and post-construction investigation of 16 Km of Kihansi Dam Access road, which is traversing the Udzungwa escarpment.

乌宗瓦陡崖（Udzungwa scarp）易发生滑坡、边坡失稳及严重侵蚀，其诱因涵盖降雨、土体赋存地层、边坡地貌特征以及陡崖范围内现有土体的总体工程特性等多项相互关联的要素。本文针对该陡崖内现有土体的部分工程特性展开探讨，精准识别并深入剖析了各类土体工程特性、侵蚀问题及边坡稳定性相关难题。本研究依托横穿乌宗瓦陡崖的16公里基汉西大坝进场公路的施工前、施工期及施工后勘察工作开展。
