[Abstract]:Based on the research and summary of classification of surrounding rock, 3D visualization of geological body and tunnel construction management system at home and abroad. Focus on the study and completion of the following content: 1) study and build the tunnel construction process, including sensors, artificial monitoring and geological advance information multi-information collection system. The system is applied to the Fusong tunnel project, and the multiple information collected is analyzed synthetically. On the other hand. The differential evolution (DED) algorithm is combined with the BP neural network algorithm and the finite element method (FEMM), respectively. The DE-ANN algorithm and the DE-FEM inversion program are implemented, and the DE-ANN algorithm is used to predict the time series of the sensor information. The mechanical parameter inversion of a large number of sections of Fusong tunnel is carried out by using the DE-FEM inversion program. Based on the analysis of the necessity of dynamic classification of surrounding rock during tunnel construction and the discussion of existing surrounding rock classification methods. The classification of surrounding rock in tunnel construction period is studied, including the classification index selected by surrounding rock classification. In this paper, a new method of surrounding rock classification based on DE-ANN algorithm is proposed, which takes geological advance prediction into account. Combined with VTK visualization, the 3D visualization surrounding rock classification technology of tunnel construction process is realized. The existing 3D geological body visualization technology is considered synthetically. On the basis of tunnel construction management system and actual engineering requirements, according to the method of software engineering, a "multi-information visualization analysis system for tunnel construction process" is developed by using C # language in .NET visual environment. The system can quickly create the required model, and has the required data management, surrounding rock classification, parameter back analysis. At last, the system is applied to Dalian subway and Fusong tunnel project. The results show that the system has high efficiency information management and timely. The function of predicting the stability of tunnel structure is analyzed accurately, which provides a powerful tool for guiding the construction and ensuring the safety and progress of the project.
