Research on Comprehensive Investigation of Diatomaceous Rock(Soil)High-speed Railway Tunnel
Comprehensive investigation of diatomaceous rock(soil)high-speed railway tunnel is studied.The methods and technologies of comprehensive investigation of diatomaceous rock(soil)tunnel are mainly introduced.Taking Feifengshan tunnel on Hangzhou-Shaoxing-Taizhou Railway as an example,a reasonable investigation scheme is designed,and the investigation results are analyzed and evaluated.The geological structure analysis,rock stratum classification,geological disaster risk assessment and treatment scheme formulation are carried out,and the suggestions on tunnel construction and support design are put forward.The research content of this paper can provide some reference for the investigation of diatomaceous rock(soil)tunnel.
