论文摘要
在本文中,作者提出并验证了一个程序,该程序打算将桥梁监控中最新的最新模型与自由可用的卫星数据相结合。通过差异SAR干涉测量法(Dinsar)技术,这是在崩溃之前创建了热那亚(意大利)莫兰迪桥的位移数据集,它使用由哥白尼开放式HUB HUB和ASFVERTEX HUB下载的图像。数据已通过ESA SNAP软件处理,以识别发生崩溃的桥梁部分中的位移速率。结果表明,采用的程序在应用程序领域具有很大的潜力,因为它代表了一种简单且廉价的方法,可以通过帮助更好地量化风险并指导有效的缓解对策来以连续的方式监视大型结构。此外,一旦经过正确验证,相同的程序可以有效地扩展到当前和将来的民用基础设施绩效估计。
In this paper the authors present and validate a procedure, which intends to combine the latest state of the art models in bridge monitoring with freely available satellite data. Through the Differential SAR interferometry (DinSAR) technique, a dataset of displacements for the Morandi bridge in Genoa (Italy), before its collapse, has been created, by using images downloaded by the Copernicus Open-Access Hub and the ASFVertex Hub. The data have been processed through the ESA SNAP software to identify the rate of displacements in the parts of the bridge where collapse occurred. Results demonstrate that the adopted procedure has great potentiality in the application field, as it represents a simple and inexpensive method to monitor large structures in a continuous way, by helping to better quantify risks and guide effective mitigation countermeasures. Moreover, the same procedure, once properly validated, could be effectively extended to the current and future performance estimation of civil infrastructures.
