项目摘要

The three stakeholders in this project, Transport Northern Ireland (TNI), Northern Ireland Rail (NIR) and the Department of Enterprise, Trade and Investment (DETI) all have one common need which this project addresses. They are required to monitor ground deformations across their geotechnical assets (e.g. embankments, cuttings and earth retaining structures) using the most efficient, cost effective methods, with a view to minimising and managing the geotechnical risk to their businesses and the road/rail users. The objective of the work therefore is to apply the methodologies that the British Geological Survey (BGS) have already developed through past research projects of assessing the deformation of geotechnical infrastructure, such as slope movement or ground subsidence, using Satellite Interferometric Synthetic Aperture Radar (InSAR). The project will validate this methodology through ground truthing, using geotechnical monitoring and high resolution photogrammetry developed by Queen's University Belfast (QUB). Through this project, the stakeholders will be able to monitor ground deformations in a more cost effective, efficient, more thorough and more robust way, and embed the use of this methodology across their organisations making a step change on how they approach assessment and manage the resilience of their geotechnical infrastructure.TNI anticipate that the use of InSAR data will help form their strategies for monitoring their geotechnical assets and will feed into the existing GIS based risk assessment methods for their infrastructure assets. The site at Straidkilly is only one of many sections along the A2 coast road that is unstable and it is hoped that InSAR will give a much greater insight into the behaviour of a variety of geohazards that impact on the road and will inform their maintenance strategies and lead to more cost effective better targeted maintenance. TNI also are committed to having a better understanding of the mechanisms of failure on the slow moving failures on the Throne Bend in Belfast. The InSAR data will allow a much better correlation between slope movement and rainfall intensity and duration to be undertaken. InSAR data will also allow better mapping of the extent and magnitude of the instability. NIR also hope to be able to correlate the slope instability against rainfall data on the Belfast-Bangor rail line. DETI anticipate that the project will validate new methods of monitoring and provide baseline data of ground motion to form the basis of future strategic decisions in regards to geohazards. The use of InSAR at sites in Carrickfergus will potentially provide greater knowledge of extent of subsidence boundaries and provide indicators to potential catastrophic collapse by analysing SAR data against periods of known rapid collapse of ground.
该项目的三个利益攸关方----北方爱尔兰交通部、北方爱尔兰铁路部和企业、贸易和投资部----都有一个共同的需要,该项目要解决这一需要。他们必须使用最有效、最具成本效益的方法,监察其岩土工程资产(例如碎石、岩屑及挡土结构)的地面变形,以尽量减少及管理其业务及道路/铁路使用者所面对的岩土工程风险。因此,这项工作的目的是应用英国地质调查局(BGS)通过过去的研究项目已经开发出的方法,利用卫星干涉合成孔径雷达(干涉合成孔径雷达)评估岩土基础设施的变形,如斜坡移动或地面沉降。该项目将利用贝尔法斯特女王大学(QUB)开发的岩土监测和高分辨率摄影测量技术,通过地面实况验证这一方法。通过这个项目,利益相关者将能够以更经济、更有效、更彻底和更强大的方式监测地面变形,并在他们的组织中嵌入这种方法的使用,使他们在如何评估和管理其岩土基础设施的弹性方面发生了一步变化。TNI预计,使用干涉合成孔径雷达数据将有助于形成他们监测其岩土资产的战略,将纳入其基础设施资产现有的基于GIS的风险评估方法。Straidkilly的站点只是A2海岸公路沿着许多不稳定路段中的一个,希望干涉合成孔径雷达能够更深入地了解影响道路的各种地质灾害的行为,并为他们的维护策略提供信息,从而实现更具成本效益的更有针对性的维护。TNI还致力于更好地了解贝尔法斯特王座弯曲缓慢移动故障的故障机制。利用干涉合成孔径雷达数据,可以更好地确定斜坡移动与降雨强度和降雨持续时间之间的关系。干涉合成孔径雷达数据还将有助于更好地绘制不稳定性的范围和程度。NIR还希望能够将贝尔法斯特-班戈铁路线上的边坡不稳定性与降雨数据相关联。DETI预计,该项目将验证新的监测方法,并提供地面运动的基线数据,以形成未来地质灾害战略决策的基础。在卡里克费格斯的地点使用干涉合成孔径雷达,将有可能提供更多关于沉降边界范围的知识,并通过对照已知的地面快速塌陷时期分析合成孔径雷达数据,提供潜在灾难性塌陷的指标。
