| Abstract: | The precise control of the flatness of the CRTSⅢ track slab of the high-speed railway is the most critical technical link in the prefabrication of the track slab,which is directly related to the smooth operation of the high-speed railway.In this paper,a large number of engineering tests have been carried out on five working conditions that may affect the flatness of the track slab.Based on data support,a comprehensive measure of track slab flatness control of"secondary sprinkling+preset inverted arch"is proposed. |
