英文摘要	The Yinxi Railway is located in the western region of China. As a high speed railway line connecting Yinchuan-Xi'an, it is of great significance for the construction of transportation facilities in western China. For cement fly-ash gravel piles and cement-soil compacted piles are used for the subgrade treatment method and reinforced cushions are set inside the embankment fill so that the upper load of the pile top plane acts as a flexible load the best cement mixing ratio of embankment fill is determined by laboratory test, and the suitable water content range of cement-soil is determined, which provides a basis for selecting reasonable construction technology for subsequent construction. Field static load test is used to test the treatment effect of composite subgrade, which proves that this kind of subgrade treatment method is an economical, feasible and effective method to enhance the bearing capacity of subgrade and treat the collapsibility of subgrade.
