Scope

Main technical content: The main technical content of this specification is as follows: 1. Clarifies the scope of application of the specification and the basic principles that should be followed in the design and construction of railway karst tunnels. 2. Specifies the principles of geological route selection for tunnels in karst areas, emphasizes the importance of risk management and advance geological forecasting for karst tunnels, and stipulates that high-risk karst tunnels should undergo design of construction disaster prevention systems and strictly implement these systems during construction. 3. Defines the main contents of geological and hydrogeological mapping for karst projects and the relevant requirements for exploration and geological testing in karst sections. 4. Clarifies the basic principles and main contents of different types of karst treatment and structural design, proposes design requirements for grouting, auxiliary tunnels, and waterproofing, and specifies the design content of safety early warning and escape systems for high-risk karst tunnels. 5. Clarifies the construction process and key points for tunnels of different karst types, stipulates the main contents of risk management, construction drainage, and disaster prevention during the construction phase of karst tunnels, and proposes requirements for the organization and management of karst tunnel construction. 6. Specifies the basic requirements and main contents of operation and maintenance of karst tunnels.
