摘要
斜坡类地质灾害具有发灾短、破坏大、高隐蔽特点,传统调查手段难以准确捕捉初期形变。以山区气田为研究对象,选取覆盖研究区91景哨兵卫星合成孔径雷达数据,基于时序InSAR技术开展潜在地灾隐患信息识别、灾害类型、时空发育规律研究,圈定有效地质灾害隐患38处,多发育于105~740 m高程和17°~37°的坡度范围内。研究表明,时序InSAR技术可有效识别山区气田地质灾害潜在隐患,可为山区气田潜在地质灾害隐患识别提供理论指导与技术支撑。
The slope geological disasters have the characteristics of short occurrence,large damage and high concealment.It is difficult to accurately capture the initial deformation with traditional investigation methods.The mountainous gas field was set as the research object,and the sentinel satellite synthetic aperture radar data covering 91 scenes in the research area,and the potential geological hazard information identification,hazard type and space-time development law were studied.38 effective geological hazards were identified which developed at 105~740 m elevation and within the gradient range of 17°~37°.The time-series InSAR technology can effectively identify the potential hazards in the mountain gas fields,and provide theoretical guidance and technical support for the identification of potential geological hazards in mountain gas fields.
