讲座题目：Measurement, Assessment, Analysis and Improvement of Transition Zones in Railway Track
主讲人： Dr. Haoyu Wang
Delft University of Technology/ Fugro
讲座内容：
Transition zones in railway tracks are locations with considerable changes in the vertical stiffness of the track support, which can be found near bridges, culverts and tunnels. In such locations, the stiffness variation and the differential settlement of tracks (uneven settlement of the track on the embankment and of the engineering structure) result in amplification of the dynamic track forces and consequent track degradation. To study the track degradation in transition zones, an integrated methodology combing an innovative experimental method and advanced numerical model has been developed. Applications of the methodology contain: assessment of the track condition in various transition zones; numerical analysis of the track behaviour and of the factors influencing initiation and propagation of the track settlement in transition zones; assessment of the performance of various countermeasures for transition zones. In addition, the effect of the moisture condition on track performance in transition zones and on the feasibility of using satellite radar for structural health monitoring of transition zones have been performed.
主讲人简介：
Dr. Haoyu Wang was on born in Shenyang, China in 1987. He received a bachelor’s degree in civil engineering and a master’s degree in railway engineering at Beijing Jiaotong University (Beijing, China). He joined the railway section of Delft University of Technology (Delft, the Netherlands) for PhD research in 2011 and worked partly as a teaching assistant in 2015 and 2016. In 2017, he worked as a consultant/railway specialist in Roadscanners (Tampere, Finland). Since 2018, he has worked as a developer/railway specialist in Fugro (Utrecht, the Netherlands). He is specialised in researching and solving problems in the railway industry, focusing on the track structure analysis, condition monitoring, and quality evaluation.
