Research on Dynamic Fine Adjustment Technology of Subway Prefabricated Slab Track Bed Based on Track Quality Index
In order to ensure the comfort of subway operation,taking the prefabricated slab track project of Shenzhen Metro Line 16 as an example,a series of adjustment and optimization processes were carried out based on the railway track quality index(TQI),and a relatively complete technical system of parameter standard,data acquisition,analysis and optimization adjustment was established,which significantly improves the smoothness of seamless lines in the section after rail welding,and effectively solves the technical problems of overall track irregularity caused by laying prefabricated track plates and 25m standard track banks in subway track engineering.Combined with engineering examples,the key and difficult problems of the application of TQI in the construction of urban rail transit structure are analyzed.
