In order to meet the needs of the rapid development of China’s tram industry, this book, through long-term research and analysis on common construction and disease treatment problems of tramway track projects, aims at the problems of groove rail wear in the design and construction of small radius curve tramway track projects, abnormal impact and wear of wheel and rail in turnout sections, and the inconvenience of traditional ballastless tramway track construction, and the stability of continuous welded rail on bridge. From the point of view of the design and construction of the existing tramway track structure, based on the random dynamic analysis method of the generalized density probability evolution theory, the vehicle-track coupled dynamics research is carried out on the wheel rail contact wear of the tramway track. From the point of view of the tram operation safety and comfort, the limit values of the tram rail wear under different curve radius conditions are proposed; According to the construction inconvenience of the existing tramway track structure and the unfavorable stress of the track structure under the uneven settlement of the subgrade, the tramway track structure has been selected and improved in design; According to the resistance test results and statistical analysis of the small radius curve rail and fastener of the tram, the stability and optimization scheme of the continuous welded rail on the bridge in the small radius curve section of the tram are systematically analyzed theoretically. The above research results have been successfully applied to Chengdu Tram Rong Line 2 and other lines, providing an important basis for the design, construction, maintenance and on-site monitoring of modern tramway track projects.

This book is suitable for front-line personnel engaged in the design, construction and maintenance of tramway track engineering as a technical reference, and also provides theoretical reference for researchers in related fields.
