Rock mass full information acquisition method and system based on digital twin model

Abstract

This invention provides a method for acquiring full information about rock masses based on a digital twin model, including: collecting drilling parameters and in-situ stress parameters; obtaining mechanical parameters at various locations within the rock mass and constructing a distribution cloud map; constructing comprehensive mechanical property parameters of the rock mass as a comprehensive evaluation standard, calculating the comprehensive mechanical property parameters at various locations within the rock mass, and constructing a distribution cloud map of the comprehensive mechanical property parameters; acquiring an image set of exposed surfaces and an image set of the borehole inner wall of the rock mass; enhancing the images to obtain corresponding fracture feature images; identifying and calculating fracture curves distributed in the images, obtaining the attitude and spatial location of the structural planes corresponding to each fracture curve, and constructing a distribution feature information set; constructing the complete morphology of the structural planes in the rock mass and establishing a three-dimensional model of the rock mass structure; and constructing a full-information digital twin model of the rock mass to intuitively present all the information of the rock mass. This invention makes the acquisition of rock mass information at engineering sites more efficient, convenient, and reliable, and has significant engineering application value.
