Abstract
In the field of high-speed railway construction, the stability and durability of subgrade engineering are directly related to train operation safety and passenger comfort. With the advancement of large-scale projects such as the Baotou–Yinchuan High-Speed Railway, the requirements for subgrade materials have become increasingly stringent. Therefore, to effectively improve the construction quality of the subgrade of the Baotou–Yinchuan High-Speed Railway, ensure the efficiency of high-speed railway construction, and lay a foundation for subsequent high-speed railway construction, this paper analyzes and studies the application of aeolian sand improved soil in the subgrade engineering of the Baotou–Yinchuan High-Speed Railway, aiming to provide reference and assistance for relevant practitioners.
