Rock mass structure detection and dangerous rock detection system and method |
| abstract |
The invention provides a system and method for rock mass structure detection and dangerous rock detection. Among them, the rock mass structure detection and dangerous rock detection system includes automatic rock mass structure detection equipment, which is provided with a three-dimensional laser scanning device and a two-dimensional image acquisition device for collecting the three-dimensional laser point cloud data and two-dimensional image acquisition equipment of the tunnel construction area respectively. an image; a server, which communicates with the automatic detection equipment for rock mass structures; the server includes a block structure three-dimensional modeling module and a block structure geometric stability analysis module. It considers the influence of the same group of structural planes inside the rock mass, the effect of new structural planes caused by blasting disturbance, and the limited scale of structural planes, and can construct polygonal pyramids and polygonal truncated blocks to be close to engineering practice; it can quickly analyze the geometric stability of any polygonal pyramid. . |
