英文摘要	The geology along the Yinxi High-speed Railway (YXZQ-5 subgrade on the Gansu-Ningxia section) is complex, with a large number of special geotechnical conditions and other unfavorable geological conditions. The hydrogeology, freezing depth, and seismic intensity along the line are different. In addition, the railway has a high design speed and high requirements for anti-deformation of the subgrade. In this paper, based on the subgrade treatment project of the Gansu-Ningxia section of the Yinxi Railway, the indoor compressive strength test of cementimproved soil and the field test of cement-improved soil were conducted. The cement mix ratios of the embankment at the bottom of the foundation bed, the embankment below the foundation bed, and the improved cushion were determined, respectively. The relationship between the optimal moisture content of the filler and the maximum dry density and the relationship between the optimal moisture content of the filler and the compaction coefficient were determined, respectively. The relationship between the ash content and the strength of cement-improved soil and the optimal moisture content of cement-improved soil were obtained. The results show that the cement-improved soil reinforcement method can better improve the strength of collapsible loess. © 2021, The Author(s), under exclusive licence to Chinese Society of Pavement Engineering.
