摘要: 川东北地区地质条件复杂、地质灾害多发,对管道的安全运营构成了一定的威胁,因此有必要采用科学有效的方法识别管道沿线地质灾害隐患。本文以达州市某油气管线为例,利用InSAR开展区域形变监测,并结合高精度光学遥感初步识别管道沿线地质灾害隐患;同时运用机载LiDAR技术获取重点区域坡体形变精细化特征及迹象,对地质灾害隐患进一步确认。结合调查资料成功识别出10处地质灾害隐患点,其中管线附近有4处历史滑坡或不稳定斜坡,3处新发现的地质灾害隐患点。研究表明,该方法体系能有效识别油气管道沿线潜在地质灾害隐患,可为管道沿线地质灾害防治提供科学依据。

Abstract: Northeast Sichuan has complex geological conditions, and frequent geological disasters. Geological disasters pose a certain threat to the safe operation of pipelines. It is necessary to use scientific and effective methods to quickly identify hidden geological hazards along the pipeline. Taking an oil and gas pipeline in Dazhou City as an example, uses InSAR to carry out regional surface deformation monitoring, and combines high-precision remote optical sensing technology to preliminarily identify geological hazards along the pipeline. At the same time, obtained the refined characteristics and signs of slope deformation in key areas by airborne LiDAR technology, and further confirm the hidden dangers of geological disasters Finally, the early identification of geological hazards is completed through field investigation. Based on survey data, successfully identified 10 potential geological hazards, including 4 historical landslides or unstable slopes near the pipeline and 3 newly discovered potential geological hazards. The results show that the proposed method system can effectively identify the potential geological hazard areas along oil and gas pipelines, and can provide scientific basis for the prevention and control of geological hazards along oil and gas pipelines.
