The Multi-source Information Fusion Geological Prediction Study On The Juchcng Tunnel

China is a mountainous country whose geological conditions are complicated. Asthe country’s rapid economic development and continuous increase in roadengineering,the number of the tunnel needed to be built is increasing.But the tunnelproject are more serious limited by geological conditions.Especially in the tunnelconstruction process, due to the complexity particularity and sudden of the geologicalconditions, the construction of the tunnel project is great impacted. So the tunnelgeological prediction has a great of study significance. When I checked a largenumber of related domestic and foreign literature, I found the source of information ofthe tunnel geological prediction are more single in previous studies. This articlecarried out the tunnel geological prediction research by Source of information fusionmethod based on three geological advanced prediction combined with the actualworks. The main work includes:(1) Through the tunnel geological disaster risk assessment, analysis of the entiretunnel paragraphs risk events that may be encountered,and delineation of therespective risk sections.There are its own risk events in each section.(2) In the risks section derived from risk assessment process, identify a typicalsection of tunnel surrounding rock in each section. Simulation analysis using finitedifference analysis software FLAC3Dthe section of the wall rock. What problem willbe happened in the excavation process, and analysis the stability of surrounding rockwith the support measures.(3)Above two-part study, we have been able to determine the actual situation ofthe tunnel surrounding rock. But the risk assessment is sketchy, can not be accuratelypointed out that what problem each wall rock may occur; the tunnel surrounding rockstability analysis can not come to the size of the unstable block. So ahead forecast ofthe geology in the construction process is particularly important. In this study, I willuse the TST to forcast the tunnel surrounding rock. To further verify and compensatefor the predicted results of the above two methods.
