Discussion on the quality control technology of railway subgrade construction in plateau altitude area
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.
