Abstract
PetroChina Southwest Pipeline Company (SPC) covers 70% of pipelines in mountainous areas. Owing to the complex topography and geomorphology, it is difficult to prevent and control the geological hazards. Traditional monitoring methods are difficult to achieve full coverage of pipelines. It is urgency to develop an economic and effective regional pipeline geological hazard monitoring system. In this paper, a new monitoring and early warning system for regional pipeline geological hazards is proposed. This system is described from the aspects of data fusion of GPS and InSAR, normalization of rainfall-deformation and combined warning model of heaven and Land. In order to verify the effectiveness and reliability of the system, the 50 km range of a pipeline is selected as the test area. The sentinel-1A, surface GPS monitoring station and rainfall quantitative monitoring station are used as data sources. In addition, the 82 potential risk areas found are monitored and warned for two years. The results verify the reliability of the system.
