Abstract: Oil pipeline as a linear project, with features on complex disaster-pregnant environment, human disturbance and much scattered disaster points, the developments of disasters are vulnerable to the effects of natural conditions change and human activities. Due to the limit of expense of disaster control, a large number of disaster points cannot be all prevented. On the other hand, land for pipeline construction is temporary, which requires pipeline management project on land occupied minimumly, with minimum possible structural measures to maximize the effect of pipeline protection. Base on the unique features of engineering and the requirements on disaster control, it is very important to establish a set of mountain hazards sentenced early identification, determining the type of disaster, prevention and control technology to adapt to the environment of pipeline engineering. On the basis of many years of research methods and techniques of mountain disaster prevention theory, combined with the practices of southwest pipeline construction, a set of theoretical methods and key technologies of mountain hazards for construction of pipeline in mountain are established, which is successfully applied to the construction and operation of oil pipeline for Sinopec to ensure that the safety of oil pipeline in the mountains.
