摘要:
采用InSAR技术对金沙铅锌矿207矿体上方地表影像进行数据处理,识别出变形较严重的区域为2^(#)、3^(#)采空区上方地表,建立2个采空区及地表三维模型,采用FLAC^(3D)进行数值模拟计算,通过数值模拟与InSAR监测协同分析,发现数值模拟结果中的2^(#)、3^(#)采空区导致的地表沉降量明显大于InSAR监测结果,说明存在地表变形继续增大的风险;数值模拟结果显示,2^(#)、3^(#)采空区顶板位移过大,采空区内部尺寸较小的矿柱上的剪应力和压应力均超过了其抗剪、抗压强度,存在失稳风险。

摘要:
传统的沉降风险评价依赖于实地测量监测技术,即使是一系列的观测点数据也难以直观地表现一定区域内地面沉降的空间分布,而有着大范围、高密度、时效性优势的基于合成孔径雷达差分干涉技术(In SAR)的地面沉降监测手段可以更加方便地提取范围内地表形变速率或形变量。通过D-In SAR和PS-In SAR技术分析sentinel-1A数据分别得到地面累积沉降量和年沉降速率信息,运用模糊层次分析法建立易发性指标,结合Python代码设计的ROC曲线利用其ACU值进行检验易发性模型的有效性;通过危险性指数法利用不同程度的降水情况获取失稳概率,得到不同降雨工况下的危险性指标,为定量的沉降易发性评估提供了依据。

摘要:
地壳深部构造动力学过程会引起山脉隆升、盆地断陷等一系列复杂的地质构造现象,在此过程中往往伴随着地震、火山等地质灾害的发生,这些频发的地质灾害严重危害着人类的生存环境。作为遥感对地观测的全新技术,合成孔径雷达干涉技术(InSAR)克服了传统形变监测手段的不足,可为高精度监测地震、火山等地质灾害形变及构建灾害机理模型提供必需的基础信息,特别是随着星载SAR传感器对地观测技术的不断发展,SAR影像时空分辨率大大提高,SAR卫星的种类和成像模式日趋丰富,这为InSAR技术持续有效开展灾害形变监测提供了广阔的应用前景。

摘要:
内蒙古鄂尔多斯市准格尔旗以丰富的煤矿资源而闻名,煤矿资源的开发利用使该地区地面沉降、地裂缝普遍发育。采用InSAR技术对准格尔旗2015年6月至今的地面沉降和地裂缝特征进行了监测。Insar成果反映准格尔旗地面变形主要有两个集中区,分别位于东部的边界区和西南部边界区,引起地面变形的主要行为是矿山开采和渣土堆填,其中分为四种类型:露天开采及填土区、渣土堆填区、地面建筑变化区、井工开采区。

摘要:
滑坡的高精度监测对于理解其运动学特征和减少滑坡造成的灾害是很有必要的,合成孔径雷达干涉测量(InSAR)技术可以为滑坡灾前形变监测提供新的技术途径。针对植被覆盖非常茂密的环境,采用基于相干性的InSAR时间序列方法,使用多轨道Sentinel^(-1) SAR影像数据集,厘定四川雅安地区汉源滑坡发生前(2018年10月至2020年8月)时空运动特征,并结合多轨道视线向形变结果提取滑坡沿坡向的运动分量。结果表明:汉源滑坡雷达视线方向(LOS)最大年平均形变速率为42.1 mm·年^(-1),滑前最大累积形变量达97 mm,共经历了形变加速和稳定两个阶段的变形;滑坡沿坡向的最大年平均形变速率为43.9 mm·年^(-1)。上述研究结果为汉源滑坡提供了第一手、相对完整的形变测量资料,展示了InSAR技术在滑坡灾前形变追溯方面的应用潜力。

摘要:
活动断层的有效定位和监测是抗灾规划、防灾减灾工作的重要前提。针对断距不明显的城市/近城区活动断层难以探测的实际问题,以美国休斯敦地区为例,利用L波段ALOS-1和C波段Sentinel-1 SAR数据,采取MT-InSAR技术获取了休斯敦北部区域地表形变速率图,并根据InSAR监测结果定位了区域活动断层。结果表明休斯敦北部区域存在3条大范围活动断层带,即Hockley断层带、Big Barn断层带和Conroe断层带。利用LiDAR、地球物理勘察绘制断层迹线和现场调查信息验证了InSAR探测断层迹线的有效性和准确性,并结合InSAR监测结果剖线及GPS时间序列数据分析了该断层系统的构造特征及时空演化规律,揭示了该地区断层的加速活动与地下水过度汲取之间有高度时空相关性,地下水过量开采促使地面沉降的发生,进而加强了已有断层的垂直运动或诱发新的断层活动。本文研究不仅监测到了休斯敦地区已知断层的活动性,还探测到其他地空技术尚未发现的活跃断层迹线,对城市规划和防灾减灾具有重要意义。

摘要:
我国四川西部高山峡谷区域地形复杂,地质灾害问题频发。公路沿线潜在地灾隐患众多,呈现出隐蔽性强、突发性高、破坏力大等特点。传统的地面地质调查手段难以早期大范围定量识别灾害隐患,而近年来InSAR技术已成为解决该问题的利器,应用潜力巨大。本文以G317线公路薛城路段的地质灾害隐.患识别为例,利用时序InSAR技术,基于2018-2022年欧空局哨兵一号(Sentinel-1A)雷达数据,成功识别到了6处典型地质灾害隐患区域,这为G317线公路及当地的防灾减灾提供了有力的定量数据分析与技术支持。结合诸多应用实例表明,InSAR技术对高山峡谷区公路工程地质灾害隐患的识别和排查优势十分突.出,具有进一步推广应用在公路工程地质灾害隐患识别排查的价值。

摘要:
On 25April 2015,an Mw 7.8 earthquake struck the village of Barpak,Gorkha district,central Nepal.This disaster claimed the lives of more than 8,000 people and devastated the city of Kathmandu and thesurrounding areas.This earthquake occurred along the collision zone between the Indian and the Eurasiantectonic plates that converge at a rate of~20 mm/yr.The stressaccumulated by this convergence is periodically released in large earthquakes that occurred in the fault systemof the Himalayan front.Actually,before the numerical values quantifying Himalayan convergence wasavailable,geophysicists and geologists in the early 1990s had anticipated great earthquake hazard wouldhappen in Nepal.During the past century,the Himalayan arc has experienced several great thrust earthquakes,such as the Kashmir earthquake,the Kangra earthquake ,the Assam earthquake and the Bihar Nepal earthquake.However,none of their coseismic surface deformations orfault slip models were extensively studied with geodetic data,except for the Mw 7.6 Kashmir event mapped bythe Aster images with the Sub-pixel correlation method.As for this Nepal earthquake,modern geodetic technologies permit a much more detailed study than was possible for anypervious large earthquakes.So this event provides an excellent opportunity to study the source parameters of large earthquake and assess the potential seismic hazard in the Northern India and Nepal.
