Abstract
A system and method for rock mass structure detection and dangerous rock detection including a rock mass structure automated detection device and a server. The rock mass structure automated detection device includes a three-dimensional laser scanning device and a two-dimensional image acquisition device for respectively acquiring three-dimensional laser point cloud data and a two-dimensional image of a tunnel construction region. The server communicates with the rock mass structure automated detection device and includes a block structure three-dimensional modeling module and a block structure geometric stability analysis module. By considering the influence of the same group of structural faces in a rock mass, the effect of a newly-generated structural face subjected to blasting disturbance, and the finite dimension of a structural face, blocks in shapes of polygonal pyramid and polygonal frustum can be constructed to comply with engineering practices, and the geometric stability of any polygonal pyramid can be rapidly analyzed.
