GIS Integration of DInSAR Measurements, Geological Investigation and Historical Surveys for the Structural Monitoring of Buildings and Infrastructures: An Application to the Valco San Paolo Urban Area of Rome

Abstract

Structural health monitoring is a crucial issue in areas with different hazard sources, such as Italy. Among non-invasive monitoring techniques, remote sensing provides useful information in supporting the management process and safety evaluations, reducing the impact of disturbances on the functionality of construction systems. The ground displacement time-series based on the analysis of Differential Interferometric Synthetic Aperture Radar (DInSAR) measurements, as well as the information about the geology of the area and the geometry of the construction under monitoring, provides useful data for the built environment’s structural assessment. This paper focuses on the structural monitoring and damage assessment of constructions based on the GIS integration of DInSAR measurements, geological investigation, historical surveys and 3D modeling. The methodology is applied to the residential area of Valco San Paolo in the city of Rome (Italy). Once the geological interpretation has confirmed the results of the DInSAR measurements, a quick damage assessment that considers all the possible conditions of the pre-existing damage at the time zero of the monitoring is shown for a damaged manufact in the area. The presented results highlight how the strategy to correlate the DInSAR-monitored ground settlements with the damage scales allows potentially to monitor continuous construction systems.

Fragility Curves Assessment of an Existing Typological Rc Building Subjected to the Combined Action of Slow-Moving Settlements and Earthquake

“…It is supposed the existence of a deformation pattern increasing from one side of the building to the opposite one, along its Y side (see Figure 1). This deformation condition can represent, for example, a subsidence phenomenon [5]. However, the identification of the causes of the displacements is not a goal of this work.…”

“…The previous damage that can affect the RC structures at the moment of the seismic assessment can be related to different hazards. At this regard, there are some applications that evaluates the structural damage in existing RC structures as consequence of displacements induced by different hazards, such as landslides [1,2] and subsidence [3][4][5]. Instead, the research on the seismic assessment procedures for existing RC buildings affected by slowmoving landslides or different hazard sources-induced displacements is very limited.…”

Application of Geographic Information System (GIS) in construction: a systematic review

“…For example, Karimi and Iordanova (2021) examined the integration of BIM and GIS for construction automation. Moreover, the integration of these two technologies has been widely studied and adopted for infrastructural planning, management, and maintenance operations in various domains of projects in the construction industry (Liu, 2017;Abd et al, 2020;Khan et al, 2021;Shekargoftar et al, 2022;Miano et al, 2022). However, this study stands out among other published articles on GIS by highlighting the key areas where GIS can be applied in different construction projects, irrespective of whether it involves BIM integration or not.…”

Historical Retaining Walls Monitoring: A Case Study of Debosquette Wall of Kyiv-Pechersk Lavra

“…The application of these methods has its pros and cons. However, a number of recent studies have shown that any of these methods can be successfully applied to monitor historic buildings [14][15][16][17][18][19][20][21][22][23][24][25]. In general, geospatial monitoring of engineering structures contains well-known stages, namely design, target setup, geodetic network creation, observations, data processing, and analysis.…”
