Abstract：Research purposes ： China is one of the countries with most serious earthquake disaster in the world. With the implement of strategy of developing western region development, the railway construction in western region mountain area will speed up. This paper analyzes the anti - seismic theories and methods of railway subgrade in high earthquake intensity area, summarizes the investigated harmful results of Wenchuan Earthquake disaster on Lanzhou and Xi′an railway bureaus, induces the earthquake disaster mechanism and the main styles for railway subgrade engineering in the mountain area, put forwards the technical measures for the earthquake 一 proof and disaster decreasing in railway subgrade engineering and studies the significance of the anti - seismic design theories and anti 一 seismic stability to guarantee the railway running smoothly.
Research conclusions ： The railway route selection in mountain area must follow the technological principle of prevention as the main. More attention should be paid to the subgrade construction and maintenance to reduce the earthquake harms to railway subgrade. The light support structure should be adopted for railway subgrade. The proposal is made the study should be done further on the design theory and the technologies of earthquake - proof, isolating earthquake and ductility design ” etc. should be introduced.
