High-speed Railway Train–Track–Bridge Systems: A Seismic Safety Technology Framework de Guo Wei

High-speed Railway Train–Track–Bridge Systems: A Seismic Safety Technology Framework

Autor Guo Wei, Yu Zhiwu, Jiang Lizhong
en Limba Engleză Paperback – aug 2026
High-speed Railway Train–Track–Bridge Systems: A Seismic Safety Technology Framework systematically constructs a seismic safety technology framework for high-speed railways, focusing on three key dimensions: catastrophe simulation innovation, in-depth mechanism revelation, and implementation of prevention technologies. In catastrophe simulations, it integrates platforms such as OpenSees and SIMPACK to develop a collaborative simulation system. The book transcends the traditional limitation of modelling tracks as inertial masses by establishing, for the first time, a seismic failure model of railway tracks. For core prevention technologies, it proposes a disruptive SI (Spectral Intensity) velocity spectrum index that dynamically maps train derailment states to the responses of bridges. These results have already been applied to hundreds of bridges along the Guiyang–Guangzhou and Shanghai–Kunming high-speed railways, surviving nine strong earthquakes of magnitude 5.5 or greater. This book serves as an integrated knowledge source for both academic researchers and professional engineers: scholars will gain proficiency in the complete "experiment–simulation–mechanism" research workflow; engineers can directly leverage SI velocity spectrum design metrics embedded in industry standards, improving efficiency in seismic-region bridge design; industry leaders can adapt maglev train-bridge coupled vibration test technologies to support national maglev R&D initiatives

  • Written by leading, award-winning experts in the field, this book systematically constructs a seismic safety technology framework for high-speed railways
  • Uniquely offers an integrated overview of seismic catastrophe simulation–mechanism–prevention
  • Integrates platforms such as OpenSees and SIMPACK to develop a collaborative catastrophe simulation system, thoroughly addressing physical validation challenges in high speed train operations
  • Serves as an integrated knowledge source for both academic researchers and professional engineers
