Abstract

The invention relates to an underground engineering rock mass structure information intelligent interpretation and cloud remote surrounding rock grading method. Research and development are performedbased on a platform C + +; the image characteristics of the fractured rock mass are fully considered; the tunnel face rock mass image is subjected to gray scale transformation, edge sharpening, secondary filtering and other operations, feature extraction of a rock mass structure is achieved based on a morphological algorithm, multi-parameter representation of the rock mass structure is conducted through the fracture rate, the fractal dimension, the surface density, the joint interval, the joint trace length, the joint middle point number and the like, and corresponding data recording and summarizing are conducted in time. The method is based on the engineering rock mass grading standard; a system reliability analysis theory is introduced for analyzing rock mass strength and rock mass integrity coefficient probability distribution rules, the performance functions of different surrounding rock grades are constructed, the reliability probability that the surrounding rock belongs to each evaluation grade is calculated through a Monte Carlo method, a corresponding rock mass structure cloud information data integration platform is constructed accordingly, and reliable data support is provided for tunnel construction and follow-up analysis.

Description

technical field [0001] The invention relates to the technical fields of tunnels, geotechnical soil and underground engineering, in particular to a method for intelligent interpretation of rock mass structure information in underground engineering and a cloud remote surrounding rock classification method. [0002] technical background [0003] In the complex and changeable natural conditions, the terrain environment where some tunnels are located is very bad, and the bad geological phenomenon is serious. In addition, due to the constraints of construction period, climate and funds, the construction conditions and conditions are usually very poor, which can easily lead to disasters and accidents. usually. Therefore, the image analysis of the tunnel face is not only required for the prediction of geological conditions during the construction process, but also occupies an extremely important position in the entire tunnel construction process. For mountain tunnels, the rock mass ...
