Based on an investigation into the geotechnical situation, the geotechnical hazards types of Sudan Block Six crude oil export pipeline were analysed and the countermeasures of Sudan six districts for Controlling pipe geological disasters were summarized. The "prevention first" policy for the pipeline of geological disaster management was carried out. And based on analyzing the geological conditions sufficiently, Scientific managements were put into effect for administering Hydraulic erosion, soil erosion of gravity, seasonal river flood erosion, rivers lateral wobble erosion, etc. Basic laws of strengthening hydrology to master seasonal stream channel evolution were illustrated. And the importance of flushing trend of piping through Nile and concrete countermeasures were elaborated.%基于原油外输管道沿线所处地质环境特征,对苏丹6区管道地质灾害类型进行了归纳分析,总结了苏丹6区为防治管道地质灾害而采取的对策措施.借鉴了管道地质灾害的治理应贯彻“预防为主”的方针,并应在充分的地质条件分析基础上,因地制宜地对水力侵蚀、土壤重力侵蚀、季节河洪水冲蚀、河流横向摆动侵蚀等地质灾害展开科学的治理.阐述了加强水文观测以掌握游荡性季节河河床演变的基本规律以及关注尼罗河穿越段管道冲刷趋势的重要性和具体对策.
