摘要研究目的:铁路隧道建设过程中，因复杂多变的地质条件，隧道施工面临较多的不安全因素，长大隧道更是如此。长沙至昆明客运专线雪峰山1号隧道具塌方、突水突泥、围岩大变形等极高风险，按I级风险管理，对该隧道围岩大变形、塌方、突水突泥等风险提出了针对性风险控制措施及风险管理基本制度，从而实现质量、投资、工期等建设目标。

研究结论:(1)准确而完整的地勘资料是风险因素识别的重要基础，风险因素识别是随着隧道地勘资料的不断完善而逐步深入，从而形成全面、成熟的风险控制措施;(2)施工图阶段、施工阶段的风险评估是风险评估的重要阶段;(3)隧道风险管理是系统工程，组织保证是风险管理成功的基础，且依赖于设计、施工、建设等单位的组织管理;(4)隧道风险管理系统的有效实施能够将建设项目的安全、质量、投资、工期等建设目标成功落地;(5)该研究成果对高速铁路隧道的风险控制与管理具有较好的借鉴作用。

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.

Key words： tunnel construction risk assessment risk management
