| 摘 要： | 大渡河加郡—得妥河段的地质环境特殊,地质灾害发育,对各种工程活动的潜在危害很大。传统的地面调查方法,由于视野所限或交通不便等给区域地质调查带来许多困难。而利用遥感影像解译调查,可以直接按影像勾绘出地质灾害的分布范围,并确定其类别和性质,同时还可查明其产生原因、规模大小、危害程度、分布规律和发展趋势。基于大渡河加郡—得妥河段的Worldview（分辨率0.5 m）遥感影像,通过对影像进行系统化处理,建立正射影像地图及三维遥感图像模型,并结合先进的工程地质分析方法,对该河段内发育的大型滑坡地质灾害的发育特征及形成机理进行了研究,结果认为,该河段滑坡灾害主要受地形地貌和脆性断层控制,地震为其触发因素。

| Abstract: | Because of the particular geological environmental setting,the geo-hazards frequently occurred in Daduhe River between Jiajun County and Detuo County,undercutting the safety of engineering activities in this area.The traditional field survey is limited in its short vision fields and inaccessible remote areas,while the interpretation based on remote sensing images could be used to obtain the distribution and scale of the hazards and then to solve the dilemma.Furthermore,the interpretation can be used in boun... |
