Problems solved by technology
[0003] The existing measurement methods and instruments for tunnel surrounding rock deformation at home and abroad can be divided into mechanical measuring instruments, electrical measuring instruments, acoustic ranging methods, laser ranging methods, etc. according to their working principles. In recent years, visual imaging technology has emerged When applied to the monitoring of tunnel surrounding rock, the formed visual image can more intuitively reflect the state of tunnel surrounding rock, but there are many problems in the processing and analysis methods of tunnel visual image data, especially for tunnel projects under complex geological conditions. It is easy to cause large errors in the evaluation of surrounding rock stability and a high rate of misjudgment

The present invention provides a method for processing the stable and visualized image data of the surrounding rock in complex geological tunnel construction, comprising: S100 collecting and saving the surrounding rock image of the tunnel according to a set cycle, and preprocessing the surrounding rock image; S200 according to the design of the tunnel Line and excavation progress, establish a three-dimensional tunnel construction dynamic model, segment and mark the tunnel construction dynamic model, associate the tunnel construction dynamic model and each segment with the corresponding surrounding rock image; S300 constructs a surrounding rock stability analysis model , identify and analyze the preprocessed surrounding rock images of each segment, and obtain the surrounding rock stability evaluation of each segment; S400 compares the surrounding rock stability evaluation of each segment with the corresponding segment of the tunnel construction dynamic model Correlation, showing the tunnel construction dynamic model and the surrounding rock stability evaluation of each section. The accuracy of evaluation is improved, misjudgment is effectively prevented, the safety of tunnel construction can be guaranteed, and accidents can be effectively prevented.
Description
technical field [0001] The invention relates to the technical field of tunnel construction safety and image data processing, in particular to a method for processing visualized image data of surrounding rock stability in complex geological tunnel construction. Background technique [0002] During tunnel construction, surrounding rock deformation is a comprehensive index that reflects the influence of various factors. The deformation of surrounding rock can be divided into surface movement and deep movement of surrounding rock. Surrounding rock surface movement refers to the distance between the roof and floor of the roadway, the distance between the two sides or the movement of a certain part measured from the surface of the surrounding rock. Compared with other information, the amount of deformation of surrounding rock is intuitive, easy to measure, and convenient for quantitative calculation, so it has gained more applications in engineering practice. [0003] The existi...
