Abstract Research purposes:The CRTSⅢ slab track is a new type of ballastless track researched and developed by China independently． However，it has some problems，such as the structural inconsistence between the bridge and subgrade section，the complex construction process，high construction cost，difficult maintenance． In order to improve the adaptability of the structure，expand the applicable scope and meet the requirement of the intercity railway at speed of 200 km /h or above，the CRTS Ⅲ slab track ＇s design，measurement and construction technologies were deeply researched and optimized for the intercity railway from Wuhan to Xianning on the basis of summing up the experiences of ballastless track design，construction and operating at home and abroad．

Research conclusions: The unified unit block structure was used for the subgrade，bridge and tunnel sections to simplify the construction technology and improve the maintainability of track structure． The high precision measurement and control system based on the technologies of the CP Ⅲ control network and free station improved the efficiency of the fine tuning by more than 50% ． The pass percent of the concrete appearance was up to more than 95% because of the perfect design of the template structure of the base and filling layers．

Key words： intercity railway CRTS Ⅲ slab track design measurement and control system construction tooling
