Ha Tai high speed rail is a high-speed railway in cold region of China. The design criteria is very strict. There is many frozen soil over cold region. The research how to reduce the amount of subgrade frost heaving over Ha Tai high speed rail is of great significance.We use a frost heave model to simulate the subgrade frost heaving in the paper.We research how the fine power content and water content influence the frost heave amount of graded crushed stone by contrast test.The result shows that the fine power content and the water content have great influence on the frost heave amount of graded crushed stone .The frost heave ratio increases with the fine powder content and the water content.
