Abstract Research purposes: Based on the theory of engineering risk, risk identification and evaluation for subgrade engineering of mountain railway were studied. And according to the assessment and evaluation for the risk, the risk prevention and control measures were adopted.
Research conclusions :(1) By using analytic hierarchy process method and expert scoring method, the weight and ordering of risk factors can be get from the qualitative analysis and quantitative comparison. (2) By using sensitivity analysis method, the main controlling factors of the risk events and the influence law of the risk factors can be found out. (3) Paste comprehensive evaluation method can be used to assess and evaluate the risk of roadbed of mountain railway. (4) The main path and possible path to ultimate risk can be found out from the risk mutual relationship diagram. (5) The ideas of risk identification and management for railway subgrade construction that formed from this paper’s research, has a guiding significance for design, construction and operation.
