Key Technologies of Main Span 150 m Continuous Rigid Frame Bridge in Urban Rail Transit

Construction of bridges in prosperous urban areas is limited by construction site, interference of ground buildings and structures, and coordination of urban landscape. Taking the 150 m large-span continuous rigid frame bridge between Heshuikou Station and Shutianpu Station of Shenzhen Rail Transit Line 6 as the case, through comparative selection of bridge design scheme and technological application of BIM (building information modeling) and key component simulation, the design scheme of the large-span continuous Y-shaped rigid frame bridge, construction steps and quality control measures of key Y-shaped components are determined, so as to avoid the interference problems that might occur during the construction of large and complex bridges. It ensures the construction quality of 150 m large-span Y-shaped rigid frame bridge, reducing construction risk and improving the construction efficiency.
