Proyecto Prometeo

The aim is to implement a continuous InSAR deformation monitoring focused on single infrastructures which provides a detailed temporal evolution of the deformation phenomena at hand.

Responsible:

Integrate in a web-based application different monitoring data and perform a first-level analysis.

Responsible:

The goal is to develop geo-mechanical models, based on the home-made Finite Element Method (FEM) code GeHoMadrid, able to reproduce past and present deformation data obtained by the implemented monitoring systems in the selected infrastructures.

Responsible:

The objective is to predict future deformation over the selected infrastructures using: i) the calibrated geo-mechanical models (O4) and ii) predefined external load scenarios: rain, temperature relying on simplified climate change setups or weather forecast or expected cyclic traffic loads.

Responsible:

End-to-end demonstration of the proposed approach in the first project Pilot, which concerns the monitoring of the infrastructure of the Catalan Railways (Ferrocarrils de la Generalitat de Catalunya - FGC). The novelty of this Pilot will be an end-to-end demonstration of the PROMETEO approach including the wide area InSAR monitoring (covering approximately 1000 km2), the automatic detections of ADAs, their intersection with the railway lines and the associated infrastructures (stations, bridges, slopes, etc.), the continuous monitoring of, at least, a selected infrastructure, the integrated modelling and the associated predictions and alerts.

Responsible:

.Demonstration of the proposed approach in the 2nd Pilot which involves a stretch of the A-7 highway (S Spain) between the Carchuna-Calahonda and Castell de Ferro exits where three road cuts have shown complex ground instabilities. An extensive site investigation campaign will be carried out to determine the geological structure of the ground, as well as to analyse the landslide kinematics.

Responsible:

Slight displacements in the viaduct of the A-44 highway that crosses the Rules Reservoir (Granada, Spain) were recently detected. The origin and evolution of these displacements are currently unknown and nor is it clear whether they could compromise the integrity of the infrastructure. Besides, a landslide also threatens the southern abutment of the viaduct. An end-to-end demonstration in this third project pilot will include InSAR analyses integrated with in-situ measurements and modelling to monitor and explain the movements of the mentioned landslide and help in the clarification of the origin of the viaduct deck deformation.

Responsible:

Demonstrate the proposed approach in the 4th Pilot, a port container terminal in the Port of Cádiz built on a reclamation land with sandy hydraulic fills on a seabed formed by soft clays. The engineered mooring structure is an array of floating concrete caissons. As settlements are expected in such infrastructures even after years of operation, and may put at risk serviceability, the Port Authority of Cádiz carried out a series of campaigns of settlement monitoring, among other surveillance work. Checking classical monitoring against continuous intelligent remote sensing tool, in particular with the InSAR technique, will provide fruitful insight on its reliability in the scope of civil engineering.
