Research methods: The analyses are made for the various factors influencing the precision of rail support platform and the effective measures for precision control in the courses of the manufacture，installation and test.
Research results: The requirement of precision control of rail support platform for track-bed template has been met through precision control and adjustment of the installation planes of the platform and template and their locations.
Research conclusions: After precision control of rail support platform for ballastless integrated track-bed template, it needs less grinding for ballastless integrated track-bed , which not only meets the requirement of construction schedule , but also reduces consumptions of toll and electric power and the manufacture cost.
