**Abstract**

Intelligent construction technology is the only way to realize the construction and upgrading of high-speed railways, and strongly supports the construction of smart railways. In terms of intelligent track design technology, the digital, dynamic and visual design of track is realized, which changes the way the traditional design unit provides only construction drawings. The design unit then provides digital track design results in addition to construction drawings, facilitating intelligent manufacturing, construction, operation and maintenance, etc. In terms of the intelligent construction of track slabs, the traditional track construction technology is upgraded by using the results of track intelligent design, and data from the total station, rail inspection trolley, note books and related tooling are automatically collected, controlled and adjusted. Data collection, analysis, statistics and prediction mechanism of the plate ballastless track are established to form a track intelligent construction technology of "data collection, data penetration, data sharing and openness, data tracking and tracing". In terms of complete sets of software for track intelligent construction, a series of intelligent design, manufacturing, construction software and complete sets of intelligent construction equipment are proposed, which greatly improves the level of intelligent construction.
