With the promotion of the layout of the national railway system in China,the construction of railways in high-altitude areas with harsh environment has been accelerated.As an important part of railway construction,the quality control of subgrade construction in high-altitude areas is very important.In order to solve the difficulties faced by the construction of railway subgrade in high-altitude areas such as seasonal frozen soil in high-altitude areas,the construction problems encountered in the actual con-struction process are analyzed and summarized by optimizing the construction technology and controlling the key points of con-struction,so as to improve the construction quality of railway subgrade in high-altitude areas and provide experience for the subse-quent construction of railway subgrade in high-altitude areas.
