Project Description:

To extend the remaining service life of bridges, detailed information of the structure's condition is essential. The "BrückenCT" project explores methods that enable non-destructive testing using X-ray computed tomography (CT) with higher resolution than conventional methods such as ultrasound and radar. The project involves developing technology and a prototype of a mobile, robot-based CT system for bridge inspection, which will be validated through field trials on two bridges. Based on the current condition, general approaches and specific recommendations for extending service life will be developed. Through simulations and the creation of a digital twin, application-specific CT systems for various bridge types and damage scenarios will be designed to enable efficient condition assessment for extending the service life of bridges shortly after the project’s completion.

Subproject: 

TUM coordinates the project and is responsible for project management and conducting reference measurements using ultrasound and radar. These measurements are simulated to enable better planning and to evaluate the expected resolution and visibility of bridge components in the measurement data. Based on these results, the added value of a CT measurement for a bridge can be determined. The simulation of ultrasound and radar also aims to enable multimodal reconstruction, thereby enhancing the depth of information in CT scans. As part of the project, two bridges will be surveyed. Based on the measurement results, the bridges' condition will be assessed, and recommendations for extending their service life will be proposed.
