Descripción del proyecto
Detección y prevención eficaces del riesgo de socavación de puentes
La socavación es un fenómeno natural y la causa más frecuente del hundimiento de los puentes. Este fenómeno erosivo del agua corriente acontece cuando el agua que se mueve rápidamente alrededor de un puente elimina el sedimento de su base, lo que crea fosos de socavación. Las prácticas actuales de gestión del riesgo de socavación de puentes son bastante ineficaces. En el proyecto RAMOBRIS, financiado con fondos europeos, se desarrollará una estrategia novedosa y multidisciplinar para evaluar el riesgo de socavación de puentes críticos. Para ello, se combinará información hidrológica, hidráulica y de socavación derivada de mediciones y pronósticos para la evaluación de la vulnerabilidad estructural. Este nuevo marco, basado en un análisis estructural no lineal para diferentes cargas hidráulicas y diferentes tipos de puentes, permitirá estimar el riesgo actual y futuro, y tener en cuenta los efectos del cambio climático.
Objetivo
The RAMOBRIS project aims to develop a novel and multidisciplinary strategy for evaluating the risk of critical bridges against scour, combining hydrological/hydraulic and scour information deriving from both measurements and forecasting, and structural vulnerability assessments. Although scour is the leading cause of bridge failures in Europe and the rest of the world, current practices for bridge scour risk management are quite inefficient, being often based on expensive, potentially inaccurate, and time-consuming visual inspections. Moreover, current procedures do not allow an explicit quantification of the expected direct and indirect losses due to the occurrence of floods. The proposed project aims at overcoming the limitations of current procedures through a novel and multidisciplinary approach exploiting the experience of the fellow in hydraulic monitoring and analysis, with the one of the host and partner organisations in structural health monitoring, structural analysis, risk assessment, flood forecasting and scour analysis. The objectives of RAMOBRIS will be [1] to critically review monitoring techniques available for assessing bridge scour risk; [2] to define a cost-effective monitoring strategy for forecasting and measuring river flow, bridge scour, and bridge-performance; [3] to define an innovative probabilistic framework for real-time scour risk monitoring, using a Bayesian approach to combine the information from heterogeneous monitoring and forecasting systems; [4] to provide a framework for bridge vulnerability assessment based on nonlinear structural analysis under different hydraulic loads and for different bridge typologies, and to estimate current and future risk of bridge collapse due to scour, taking into account climate change effects. The research achievements will significantly contribute to the objectives of the European Programme for Critical Infrastructure Protection and to achievement of a resource efficient economy and society.
