Abstract Research purposes: The information of risk management research is limited. And the risk management system has not been formed. So it is important and significative to establish the risk prediction and evaluation theory and realize the risk prevention and management for the railway embankment. This paper studied the method of risk prediction and evaluation theory for railway embankment, and analyzed the risk of one railway embankment. All above can provide reference and guidance for the research of risk management techniques of railway subgrade engineering.
Research conclusions: (1) In the paper, a comprehensive analysis method with “analytic hierarchy process + expert investigation + fuzzy evaluation" is put forward for analysis and calculation of the risk of railway embankment engineering and the specific steps have been given. (2)It is suggested to class risk factors of railway embankment as slight degree, mild degree, moderate degree, severe degree and catastrophic degree and the corresponding treatment measures are put forward. (3)The calculation result shows the weight of seismic risk factor is maximum in the risk factors, therefore, the corresponding risk treatment measures shall be taken in the design of embankment in the seismic area.(4)The comprehensive analysis method with “analytic hierarchy process + expert investigation + fuzzy evaluation” is characterized by distinct levels，clear steps and quantitative analysis of risk, which can be used for identification and analysis of subgrade engineering risk of railway and highway.
