Precise control of track structure settlement is essential to guarantee the steady and secure functioning of high-speed maglev trains. An overview of the features and progress of maglev track structure settlement is provided. In order to address the need for settlement control of maglev track structures at 600 km/h, an analysis is conducted on the technical challenges and difficulties, leading to the proposal of development prospects and suggestions for settlement control of high-speed maglev track structures. These suggestions include the creation of a high-precision analysis and calculation theory for settlement of structure-foundation-soil composite system, the development of an innovative high-speed maglev track structure and foundation system, and the implementation of autonomous control technology for settlement of high-speed maglev track structures. The results can provide technical support for the design and construction of 600 km/h maglev track structure.
