Problems solved by technology
[0004] (1) The traditional projection method can only perform projection judgment in a single direction, and cannot conduct a comprehensive analysis of the rock mass to be measured, which is prone to safety omissions;
[0005] (2) At the same time, after the projection, there is a lack of intuitive expression, which is not conducive to engineers to quickly understand the situation of the rock mass

The invention discloses a total space stereographic projection method. The total space stereographic projection method comprises following steps: S100, rock body occurrence is measured, wherein a specialized compass apparatus is adopted to measure a rock body to be measured so as to obtain the determined occurrence data of the rock body to be measured, and the measured data is recorded; S200, a stereographic projection coordinate system is established, wherein an Oxyz coordinate system is established, the north direction is taken as the x axis positive direction, the east direction is taken asthe y axis positive direction, the vertical upward direction is taken as the z axis positive direction, and the projection coordinates of projection positions are calculated; S300, a stereographic projection net is established, wherein the stereographic projection net is composed of a stereographic large circle, the east-west direction diameter, the north-south direction diameter, a plurality oflongitude large circle arcs, a plurality of latitude small circle arcs, and a stereographic plane large circular center; and S400, total space protection is obtained, wherein the total space protection is composed of two symmetrical half space protections of two opposite directions. The total space stereographic projection method can be used for comprehensive analysis of rock body practical parameters, determining rock body stability, providing engineering construction with theory base, and ensuring construction safety.
Description
technical field [0001] The invention relates to the technical field of geological engineering, in particular to a full-space stereographic projection method. Background technique [0002] Engineering is the application of science and mathematics by which the properties of matter and energy in nature can be made through various structures, machines, products, systems and processes in the shortest time and with the least human and material resources. Something efficient, reliable, and useful to humans. The general term for various disciplines formed by applying the theory of natural science to specific industrial and agricultural production departments. During outdoor construction, it is often necessary to test the rock mass under construction to judge [0003] Projecting planes and lines on the equatorial plane of the projection sphere is used in structural geology to solve the angle and orientation of geological structures. The basic principle is to put the surface and lin...
