**1. Introduction**

Ballastless track is one of the core technologies of high-speed railways. The track structure directly acts on the substructure, the deformation of the substructure will directly affect the track smoothness and stability, and the construction quality and accuracy will directly affect the safety and comfort of high-speed train operation. Track engineering has the following characteristics (**Figure 1**) [1, 2].

1.High precision requirement: The required accuracy of rail laying is 1 mm, the manufacturing accuracy of track slab is 0.5 to 1 mm; the accuracy of the

molds is 0.3 to 0.5 mm; The thickness accuracy of cast-in-situ concrete is 0 to 10 mm.


A new round of scientific and technological revolution and industrial transformation is emerging; artificial intelligence (AI), big data, cloud computing, Internet of Things (IoT), building information modeling (BIM), Beidou Navigation satellite system (BDS) and other new technologies are accelerating breakthrough applications, and human society will quickly enter the era of intelligence [9, 10].

With the rapid development of high-speed railways and artificial intelligence and other high-tech higher requirements have been put forward for the supervision ability, intelligence and recording of information for high-speed railway construction on site. At the same time, the development of high-speed railways is turning to pay more attention to delicacy management, the development quality, the service level, and

solving the deep-seated and overall problems, further improving the modernization of construction and the management level of the high-speed railway.

The design realization of the traditional construction management mode of highspeed railway track engineering shall be delivered in the form of construction drawings, and the construction organization constructs according to the drawings. The construction level of information gathering and intelligence is too low. Research on intelligent construction technology is helpful to improve the quality of track construction, enhance the efficiency of operation, ensure project progress and control construction cost.

This chapter introduces the intelligent technology of ballastless track construction for high-speed railways, and intellisense, mobile internet intelligent transmission technology, intelligent analysis and control technology introduced to the track construction process. This mainly forms the dynamic design technology of the ballastless track construction process, the measurement and control technology of high-speed railway ballastless track construction based on data driven and the intelligent control technology which realize the high precision control and automatic measurement and control of ballastless track construction processes, lays the foundation for intelligent railways, and promotes the development of railway construction to an intelligent approach (**Figure 2**).
