| 摘 要： | 我国川西地区近年来发生多次7.0级以上地震，诱发大量震裂山体。震裂山体有着高位隐蔽性特点，对灾区人民的生命财产造成了极大威胁。InSAR技术对于识别潜在崩滑地质灾害有着较好的应用效果，本文采用InSAR技术与地表专业位移监测方法对杂谷脑河左岸进行地质灾害识别。研究结果表明:通过InSAR技术识别出该区域存在3处变形体，其中黄泥坝子滑坡在2017年8月10日产生整体滑动，西山村滑坡仍在蠕滑变形，裕丰岩变形体(疑似滑坡体)为蠕滑变形；通过地表专业位移监测结果，显示西山村滑坡变形趋势与InSAR结果一致，验证了InSAR结果的合理性；西山村滑坡体失稳后堆积体运动演化过程具有阶段性特征，即加速滑移阶段、减速滑移阶段、渐进稳定阶段。

| Abstract: | In the western Sichuan region of China, there have been many earthquakes of magnitude 7.0 or higher in recent years, which have induced a large number of shattered mountains. The shattering mountain has a high hidden feature, which poses a great threat to the lives and property of the people in the disaster area. InSAR technology has a good application effect for identifying potential glide disasters. Therefore, this paper applies InSAR technology and surface professional monitoring method to identify geological hazards on the left bank of Zagunao River. The results show that there are three deformed bodies in the area by InSAR technology. The Huangniobazi landslide has an overall sliding on August 10, 2017. The Xishancun landslide is still creeping deformation, and the Yufeng rock deformation body (Suspected landslide) is the creep deformation; the results of analysis of the surface displacement monitoring show that the deformation trend of the Xishan Village landslide is consistent with the InSAR results, which verifies the rationality of the InSAR results. The evolution process of the sediments after the instability of the Xishan Village landslide has periodic characteristics, that is, the acceleration slip phase, the deceleration slip phase, and the progressive stabilization phase. |
