Abstract Research purposes:Railway tunnel construction process，due to the complex geological conditions，tunnel construction faces more insecurity factors，especially long tunnel. Xuefeng Mountain Tunnel No. 1 of Changsha to Kunming Passenger Dedicated Line faces many high risk factors，such as landslides，sudden inrush of water and mud， large deformation of surrounding rock. According to grade I risk management，the specific risk control measures and risk management basic system are proposed for the tunnel surrounding rock deformation，landslides，sudden inrush of water, mud and other risks，in order to achieve quality，investment，construction period and other development goals.
Research conclusions:(1)Accurate and complete information is an important basis for the geological survey to identify the risk factors. With the continuous improvement of the tunnel geological survey data, the risk factor identification is gradually deepened，to form a comprehensive，sophisticated risk control measures. (2)Risk assessment of construction drawing stage and construction phase is an important stage of the risk assessment.(3)Risk management of tunnel is a system engineering, organization guarantee is the foundation of risk management success，which depends on the organization and management of design，construction，and construction units. ( 4)Effective implementation of the risk management system will make sure the tunnel safety，quality，investment，construction period and other ground targets of construction projects met successfully. ( 5)The research results can provide a good reference for the risk control and management of high speed railway tunnel.
