Based on the construction of high risk tunnels in Guiguang-Guangzhou high-speed railway, several new technologies were developed for high-risk tunnel construction. First, an integrated advanced geological prediction was tunneling karst area. Then, a system ventilation by involving dedusting technology proposed and used field, which received good air quality. Finally, method to minimize distance between working face invert installation optimizing adopting micro bench method. Applying project obtained excellent result. The achievement this study would be able provide valuable reference similar projects future.
