Problems solved by technology

At present, the traditional surrounding rock classification method is difficult to classify surrounding rock because there is no accurate constitutive relationship between the classification index of surrounding rock and the grade of surrounding rock. True and accurate response Surrounding rock grades have not yet found an exact answer, and there is no clear boundary between all levels of surrounding rock

Embodiment Construction

[0042] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0043] At present, the methods of surrounding rock classification mainly include three basic methods: qualitative, quantitative, and a combination of qualitative and quantitative.

[0044] Qualitative classification of surrounding rock grades relies heavily on the components of knowledge and experience, and there are certain human subjective factors and uncertainties. In actual use, there are often inconsistencies. Depending on the difference in cognition and experience of survey personnel, the same surrounding rock may be determined. Different levels of judgment. With the qualitative classification of surrounding rock categories, sometimes the surrounding rock classifications made by different personnel may be quite different, so this method has...

Abstract

The invention provides an identification method for tunnel surrounding rock classification, which comprises the following steps of acquiring while-drilling parameter data of a rock drill during tunnelface drilling and rock geological information at a position corresponding to the while-drilling parameter data, and carrying out standardization processing on the while-drilling parameter data; carrying out data analysis on the standard-processed while-drilling parameter data, and determining the relationship between the while-drilling parameters at the same position and the surrounding rock strength in combination with the rock geological information; acquiring a tunnel face image of the tunnel face, performing image processing on the tunnel face image, and determining a discrimination relationship between the tunnel face image at the same position and the rock integrity degree; and carrying out grading judgment on the tunnel surrounding rock by integrating the relationship between the drilling-while-drilling parameters and the surrounding rock strength at the same position and the judgment relationship between the tunnel face image and the rock integrity degree at the same position,and determining the grade of the tunnel surrounding rock. According to the method, the grade of the tunnel surrounding rock can be determined through the collected tunnel face image, the drilling parameter data and the rock geological information.

Description

Technical field [0001] The invention relates to the field of surrounding rock detection, in particular to an identification method and device for tunnel surrounding rock classification. Background technique [0002] In recent years, with the development of high-speed railways, the construction of mountain railways has increased, and the construction of corresponding tunnels has also increased. The classification of the surrounding rock of the tunnel is the basis for selecting the construction method, the basis for determining the type and size of the lining structure, and determining the structural load. At present, the traditional surrounding rock grading method is difficult to classify surrounding rock because there is no precise constitutive relationship between the grading index of surrounding rock and the surrounding rock grade, or that is, what index can be used. A true and accurate response to the level of surrounding rock has not yet found an exact answer, and there is n...
