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.
