摘要：
China's mountain tunnel project has made great achievements after more than 30 years of rapid development. However, the various accidents and risks accompanying the accomplishments remain severe. To date, the rapid development of risk assessment, management theory, and practicality have become indispensable parts of the construction process and contribute immensely to the safety of the staff, thereby reducing economic losses and protecting the natural environment in the tunnel construction. Risk assessment, management theory, and practicality have encountered many issues in the application process, such as the lack of a clear and complete risk management process and standardized risk assessment indicator system. To overcome these problems, a complete process for the risk assessment and management of a mountain tunnel construction by summarizing and promoting the risk assessment process of the existing standards has been established in this study. Moreover, the identification of risk factors in this process is elaborated upon with regard to risk source identification, risk event identification, and the relationship between them. The existing risk assessment index system was perfected by introducing soft science quantitative analysis methods, building an accident case database and practical software platform, adopting the methods that involve selecting indicators reasonably, introducing indicator weights, and normalizing a scoring standard. Thus, a complete construction safety risk assessment and management theory system for mountain tunnel construction was established. This study considered the overall risk assessment and rockburst risk assessment systems as examples to elaborate upon the ideas of the proposed assessment systems. Hence, the practical application of risk assessment and management theory in particular projects could be promoted. © 2019, Editorial Board of Journal of Tianjin University(Science and Technology).
