[Abstract]:In the excavation process of high risk tunnel group of passenger dedicated line, it is the mainstream trend to use advanced geological forecast technology to improve information level and carry out risk control. As far as the whole railway line is concerned, The safe progress of tunnel construction plays a decisive role in the early opening time of railway. It is also of great significance to the connection construction of national large railway network. By using geological advanced forecast technology, the abnormal hydrogeological conditions of rock mass engineering in front of the surrounding rock of tunnel excavation face can be detected in time, and the engineering measures can be taken ahead of time. Through geological sketch of surrounding rock, data collection of field exploration, basic theory analysis and comprehensive simulation of mathematical model, this paper combines the geological conditions of tunnel group of Xicheng railway passenger dedicated line with the geological conditions of tunnel group of Xicheng railway passenger dedicated line. Referring to the engineering hydrogeological changes of surrounding rock mass during tunnel excavation, this paper makes a deep study by using advanced detection method. The main contents and results of this paper are as follows: 1. The theoretical basis of TSP tunnel Seismic prediction method is discussed emphatically. The composition, working principle, field data acquisition process and software interpretation of the equipment are introduced in this paper. The structure and working mode of ground Penetration radar prediction system are introduced. Based on the initial detailed prospecting data, this paper describes the working mode of comprehensive geological advance prediction using TSP and GPR detection techniques. 2. The study object is the Great Qinling Tunnel, a group of tunnels in the west of the passenger dedicated Line. The detailed geological survey data and tunnel geological hazard analysis are carried out, the hydrogeological conditions of Daqinling tunnel are studied, and the bad geological hazards. 3. The basic theory and method of fuzzy mathematics are discussed. According to the "fuzziness" relation between the classification characteristics of rock burst and the corresponding evaluation indexes during the excavation of tunnel surrounding rock, the fuzzy information classification system of rock burst hazard grade is analyzed and studied. To evaluate the risk of rock burst in tunnel construction.
