Abstract Research purposes: The risk management technology for the railway subgrade engineering is just in the beginning stage and there is a little reference information on it． There are many problems in the establishment of the risk database， the identification of the risk factors， the establishment of the prediction model， the quantitative characterization of the dynamic changes of the risk factors，the recognition of the hazard － affected body and the quantitative evaluation of the vulnerability． Aiming at the problems mentioned above，and taking an expansive soil nailing wall for the cut slope as an example，this paper expounds the risk management process and introduces the scientific risk management system composes of the analytic hierarchy process method，expert investigation method and fuzzy evaluation method and its operation steps for providing the reference and guidance to doing the research on the risk management technology for railway subgrade engineering．

Research conclusions: The risk management system composed of the analytic hierarchy process method，expert investigation method and fuzzy evaluation method has the characteristics of the distinct levels，clear steps and detailed analysis． The analysis results accord with the real situation，so it is reliable． The natural risk，environmental risk， construction risk and design risk have the big influence on the risk assessment results of the expansive soil nailing wall． Therefore，on fully consideration of natural and environmental factors，the reasonable design and strictly construction according to the design are the key points to reduce the collapse risk of the expansive soil nailing wall．

Key words： expansive soil cut slope soil nailing wall risk management
