Background
In the rock engineering fields of mining, tunnel excavation, research and development of radioactive waste disposal libraries and the like, the distribution condition of a rock mass structural plane is one of the main factors of engineering stability. The three-dimensional fracture network modeling technology and the rock mass structural plane survey need to acquire the spatial position or the occurrence of the structural plane. The current rock structural surface measuring methods mainly comprise a line measuring method, a window statistical method, a drilling directional coring method, a photogrammetry method, a three-dimensional laser scanning method and the like. The line-measuring and window-counting methods measure structural surfaces by contact of a tape measure and a compass, which is inefficient, time consuming and does not allow for the measurement of difficult-to-contact structural surfaces. The directional core drilling method obtains the attitude by measuring the structural surface of the rock core, and the method has lower accuracy and limited measuring range. Photogrammetry and three-dimensional laser scanning both adopt non-contact high-precision mapping and photographing equipment, and have complex operation and heavy and expensive equipment.
