Full Description
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 the implementation of prevention technologies. The book transcends the traditional limitation of modeling 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.
