Embodiment 1
[0035] A rapid classification method for tunnel surrounding rock, such as figure 1 shown, including:
[0036] S1: Determine the rapid classification index of surrounding rock.
[0037] In the above method, the classification index is determined by analyzing the basic theoretical methods of tunnel surrounding rock classification commonly used; the commonly used basic theoretical methods of tunnel surrounding rock classification include RMR, Q, RMi, GSI and BQ; in this embodiment, the BQ method is adopted, which is in It has more advantages in quick judgment. Advantage 1: The quality index of rock mass and the quality index of engineering rock mass are considered separately; It has quantitative and qualitative reference methods, quantitative indicators are convenient for rapid judgment by computer, and qualitative indicators are convenient for later verification of the judgment results output by the grading equipment.
[0038] The basic quality index of rock mass in BQ method ...

Abstract
The invention discloses a tunnel surrounding rock rapid grading method and system. The method comprises the steps of: determining surrounding rock rapid grading indexes; testing the integrity index of the rock mass; testing the rock hardness index; determining a correction index; quickly judging the surrounding rock level according to the index value based on a neural network; outputting a judgment result; whereina tunnel surrounding rock rapid grading system comprises an acquisition module, a data processing module, a data analysis module and an output module. The acquisition module performs data acquisition through hardware equipment; the data processing module comprises morphology data, laser echo data and correction data; the data analysis module performs analysis by constructing a neural network; the output module comprises a terminal and a cloud server; according to the method, the surrounding rock can be accurately and rapidly graded, and the judgment accuracy can be ensured through the neural network; different surrounding rocks can be quickly and automatically graded, so that the construction cost is effectively reduced; and the working efficiency can be effectively improved, and the working period is shortened.
Description
technical field [0001] The invention relates to the field of tunnel engineering, in particular to a method and system for quickly grading tunnel surrounding rock. Background technique [0002] Rapid grading of tunnel surrounding rock is the prerequisite for realizing reasonable and accurate support design and ensuring the safety of on-site construction. According to the "Engineering Rock Mass Classification Standard", the basic classification of surrounding rock can be determined by the hardness of the rock and the integrity of the rock mass. The hardness of the rock can be determined by the uniaxial saturated compressive strength, and the integrity of the rock is divided according to the integrity index. Obviously, the traditional division method needs to be realized based on indoor rock tests, and the judgment period is long and the efficiency is not high. [0003] With the development of scanning technologies such as 3D topography and 3D laser, the efficiency, portabili...
