超前地质预报技术在铁路隧道动态信息化施工中的应用
|
摘要
由于隧道地质条件的复杂性,前期的勘察、设计与实际开挖揭露的地质情况常常出现偏差现象,不能满足隧道施工对工程地质信息实时、准确把握的需要。文章结合新古田隧道工程实例,介绍了在铁路隧道施工过程中采用动态设计的理念。使用超前地质预报技术与现场地质调查相结合的方法,能及时优化隧道前方围岩级别,对原设计进行动态调整。通过动态调整围岩级别,能够相应地及时调整施工方法和支护措施,确保施工的安全性和经济性。
Because of the complicated geological conditions of tunnels, the geological conditions determined in preliminary investigation and design are often different from those found during actual excavation, which cannot meet the requirements for accurate, real-time geological information for tunnel construction. In this paper, the Xingutian tunnel is taken as a project example to introduce the concept of dynamic design applied in railway tunnel construction. Combining the advance geologic prediction technique with geological field surveys, the classifications of surrounding rocks in front of the tunnel can be modified in time, and the original design option can be adjusted dynamically, allowing the corresponding construction and supporting methods to be adjusted in time so as to ensure the safety and economy of construction.
