  1. 1. U - Net Based Crack Detection in Road and Railroad Tunnels Using Data Acquired by Mobile Device

    University essay from KTH/Geoinformatik

    Author : Kepan Gao; [2022]
    Keywords : U-Net; deep learning; tunnel monitoring; structural health monitoring; crack detection; mobile mapping system;

    Abstract : Infrastructures like bridges and tunnels are significant for the economy and growth of countries, however, the risk of failure increases as they getting aged. Therefore, a systematic monitoring scheme is necessary to check the integrity regularly. READ MORE

  3. 3. Structural Health of a concrete tunnel lining under complex in situ loading

    University essay from KTH/Bro- och stålbyggnad

    Author : LEONARDO DALLA ROSA; [2019]
    Keywords : ;

    Abstract : Supporting structures were designed for a utility tunnel in hard rock which was to be intersectedby some road tunnels. With the intersections involving partial overlapping between the idealcross-sections, a concrete lining and post-tensioned steel cables were added to support theutility tunnel prior to the excavation of the road tunnels.

  4. 4. Quantifying uncertainty in structural condition with Bayesian deep learning : A study on the Z-24 bridge benchmark

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Steinar Asgrimsson; [2019]
    Keywords : Bayesian Deep Learning; Autoencoders; Bridge Structural Health Monitoring; Bridge Damage Detection;

    Abstract : A machine learning approach to damage detection is presented for a bridge structural health monitoring system, validated on the renowned Z-24 bridge benchmark dataset where a sensor instrumented, threespan bridge was realistically damaged in stages. A Bayesian autoencoder neural network is trained to reconstruct raw sensor data sequences, with uncertainty bounds in prediction. READ MORE

  5. 5. Terrestrial Laser Scanning for Wooden Facade-system Inspection

    University essay from Luleå tekniska universitet

    Author : Alexander Scharf; [2019]
    Keywords : laser scanning; facade monitoring; point cloud; wooden facade;

    Abstract : The objective of this study was to evaluate the feasibility of measuring movement, deformation and displacement in wooden façade-systems by terrestrial laser scanning. An overview of different surveying techniques and methods has been created. READ MORE
