NEW TECHNOLOGIES FOR THE STUDY AND MONITORING OF LANDSLIDES AFFECTING CRITICAL TRANSPORT INFRASTRUCTURE

Abstract

Landslide monitoring is becoming increasingly important for mitigating and eliminating risks to critical infrastructure (roads and highways, railways, waterways, energy transmission networks, etc.).This work aims to present the technique of electrical resistivity tomography (ERT) for the analysis and monitoring of landslides in conjunction with radar satellite data, InSAR (Interferometry for Synthetic Aperture Radar).The ERT and InSAR methods are complemented by the methods of automatic continuous monitoring during the execution and in the exploration of critical structures and infrastructures by introducing the real-time warning component of the events in progress. By applying these modern techniques, it is possible to reduce the geotechnical risk in the design phase, it is possible to reduce the construction and operation costs, but also to avoid losses due to landslides that can short-circuit critical transport infrastructures.
