Currently, over half of China's trunk railways are located in permafrost regions. But to tackle the railway subgrade disease has always been the difficulty in the railway construction there. The influence that the dynamics performance of frozen silty clay has on permafrost subgrade is an important component in the researches towards permafrost subgrade. In this paper, the dynamics performance of frozen silty clay in permafrost regions is studied based on the indoor dynamic triaxial test at a low temperature, and at the same time, by studying the influence that several factors like cyclic matrix, confining pressure, temperature and frequency have on relevant dynamics parameters, basis can be provided for the transformation and settlement mechanism of permafrost subgrade as well as for the analysis towards the permafrost's influence on vibration response under train load, and it offers much reference value to permafrost subgrade's design.
